Raging Shin Megami Tensei fangirl here. Anybody played the personas? Any of the five games (The latest was persona 4 for 2 was in two seperate games).
Or, for that matter, Nocturne, or, if you're from my country, Lucifer's Call.
both revolve around summonin/collecting demons in a manner reminscent of pokemon. A manner, also, that could scar any pokemon fan for life.
Hilarious moment in Persona: I went to fuse nekomata and Apsara, two rather sexy babes, to make a stronger persona. It was Legion (a humungous and disgusting ball of limbs and faces) and you know what its next move was? Sexy dance.
