Megaman X: [Platformer] I love the Megaman games, one of the first videogames I played on the NES was the original Megaman. Blue is my favorite color and I saw myself as Megaman as a child. Megaman X is a refinement of the mechanics introduced in the Classic series. And the first one is arguably so close to perfect. My favorite is X5 and the overall best is X4. But, the first one has the special charm and added bonus of also working as a completely stand alone title, when having the armor capsules hidden and scattered made sense. Easily the best soundtrack of the series and for a series famous for great level design, it has one of the best.
Baldur's Gate: [cRPG] The Bhaalspawn duology is fantastic and to this day still the best D&D experience in videogame format. I specially prefer 1 over 2 because you start at Level 1 and are even afraid of forest wolves. It feels like your first character when you were a 12 year old kid discovering D&D for the first time. That magic feeling of wonder about a fantastical world. I also like the more restrain magic that has to be more strategic and rewards preparation and having the martial characters not require 5 tons of pre-battle buffs to survive. You can employ actual tactics like choke points and flank maneuvers.
Diablo II: [ARPG] While Diablo 1 was awesome and had an unmatched atmosphere and is one of the best action dungeon crawlers, Diablo II refined those mechanics, much like Megaman X did for Megaman Classic, and turned it into something really special. Diablo II really has it all. The action, the music, the atmosphere, the graphics, the classes, the co-op and the single player storyline. If there was ever a game that deserved the title of "Masterpiece" I have no regards about the claim for this game.
Final Fantasy IX: [JRPG] Out of all the anime games from Japan that mix D&D mechanics, later known as "JRPGs", Final Fantasy has always been the most special series of them all. And amongst all the Final Fantasy games, IX is the most Final Fantasy of them all. A tale of friendship, sorrow, existentialism and what means to truly be "alive" wrapped in all the melodramatic glory that made anime famous. And most important of all, it is extremely sincere. Not a hint of shame or ironic humor. Hironobu Sakaguchi's swan song is the game that does the "JRPG" task better than any other and is rightfully the last title of the series and stands above the rest as its Champion. Never again will we see this magic every reproduced. It is
the Final Fantasy.
Final Fantasy Tactics: The Zodiac Brave Story: [Tacticool] This game uses the "war of the roses" plotline and adds its own anime spin to it. But the key here is the gameplay. Elevation, weather effects, spells have casting times and can be interrupted, flanking matters. It is very close to D&D on a grid instead of the theater of the mind that is more closely emulated by BG. While sharing a lot of DNA with Tactics Ogre and the story in Tactics Ogre is objectively better, the abilities, robust class features and the way you can add "multi-class" features to your character via the ability system edges FFT for me over TO. Both greats of the genre that have not been toppled to this day.
Mount & Blade Warband: [3rd person ARPG/Strategy mashup] No game has truly tapped into this style of gameplay other the M&B series. Starting as a lowly peasant on foot or even a betrayed noble on a horse, you and you alone set out on a journey to go from Adventurer to Conqueror to King and even Emperor of all Calradia. From 3rd person action RPG into big medieval RTS into grand strategy. Warband is the only one that has the complete package. Alone, the game is rough around the edges but with mods it becomes something truly special that no game has been able to replicate.
Ace Combat Zero: The Belkan War: [Arcade Fighter Jet] The reason the Ace Combat series is so beloved is because they mixed arcade fighter jet gameplay with just a sprinkle of sim and then a heavy dose of Top Gun. All the games are essentially unofficial game adaptations/spin-offs of Top Gun that put the Player in the cockpit. The music, the cheese action movie dialogue, the flight model that is just realistic enough to feel right but arcade-y enough to properly let you play into the power fantasy of being the leading man in a Top Gun movie. There have been other arcade fighter jet games that pale in comparison and while its nowhere near a proper fighter jet sim like DCS, it never intended to be anything more than Top Gun: the game series. Out of these games, the best one is Zero, which introduces a mechanic where you can damage enemy planes enough to have them become ineffective to keep fighting and you can decide to spare them or kill them. It also has the best soundtrack in the series which already has great soundtracks and the story of Galm 1, callsign "Cipher" who canonically flies an F-15C Eagle, the BEST fighter jet
EVER created by the UNITED STATES of
AMERICA and as such, he is the best protagonist in the entire series by virtue of this alone.
HBS Battletech: [Turn-based Strategy] Harebrained schemes was a game developer studio which was led by Jordan Weisman, the original creator of Battletech. They created an excellent adaptation of the tabletop into a videogame format. It has both a story campaign and a superb free-form career mode that lets you roam across the Inner Sphere, running a mercenary company as you see fit. And then you can add the RogueTech mod which improves the gameplay and the mechanics to make it
almost 1:1 to the tabletop. Take jobs, get salvage, build your big stompy robots, customize them in the Mechlab to fit your specifications and mission priorities, recruit pilots, train them, manage your finances so you can continue getting more and more new toys to play with.
Mechwarrior 5: [Mech-sim 1st person shooter] And the companion to Battletech is Mechwarrior. In the same universe but now you are inside the cockpit of the big stompy robot. 4 has always been my favorite but now with the most recent DLCs and mods, 5 has been elevated into the best way to get inside a BL-6b-KT Black Knight and light everything on fire with its powerful energy weapons loadout in VR. Just like the HBS game, there is a full story driven campaign and also an open sandbox career mode that lets you roam free across the Inner Sphere. The timeline progresses and new tech becomes available as it is rediscovered. The new DLCs now include the timeline all the way to the Clan Invasion, the best era of Battletech. While there's a lot of overlap between the two games as they both let you play out the fantasy of running a mercenary company in the Battletech universe, they are completely different genres, with HBS Battletech being a slow, methodical, turn-based strategy game while Mechwarrior is a fast-paced, mech-sim first person shooter. If HBS Battletech is about being a commander of a mercenary company, leading your pilots through comms with a bird's eye satellite feed, MechWarrior is about being the leader on the frontlines inside the cockpit of the Command Mech of that same mercenary company.
I tried to do only one game from a series and one genre per game so some great games that I wanted to include didn't made the cut. I thought this was just a gimmick but I ended up enjoying the exercise of having to come up with nine great games that I love while also limiting myself to one of each genre and one of each series. And no, FFT is a spinoff series with three games as of yet and is a tacticool game based on a grid, not a JRPG like FF IX so there's no overlap.
