Fire Emblem: Radiant Dawn was the epitome of this for me.
Part 1, Dawn Brigade: I hate this, I hope Micaiah dies horribly at the end, along with her entire band of useless dickheads.
Part 2, Crimean Rebellion: Heh, pretty fun... Not the best, but certainly entertaining...
Part 3, Ike's Mercenaries vs Dawn Brigade: I fucking LOVE this game!
