Fun mechanics in tactics games

[Norfleet]

Slightly related: are there any tactics games that give an advantage for how targets are selected across turns? For example, +10% damage because an ally already attacked this creature this turn. Or maybe more sensibly less damage for each subsequent attacker since focus fire is usually the dominant strategy without further incentives.

Suppression effects tend to promote this over focus-fire because if everyone focus fires on one target, that target might be permanently suppressed, but every OTHER target isn't suppressed at all, whereas if you spray boolet everywhere, all enemies can be suppressed.
