Those are some interesting choices, but I see the pattern of Assimilate everything and HUUURRR HUURRR which I have no clue about. Oh and about the mature pok'emon thing I just meant a pok'emon style of game for an older audience not what you were thinking. Let me add a game in the SMT series that has a weird idea.
Digital Devil Saga 1&2: Tell everyone in the Lylat system that it does not exist, and that it is the creation of beings that the characters look like. Then when Star Fox escapes the imaginary Lylat they are told that their creators live in a world that also does not exist and was created by an all powerful being which they must confront to stop Corneria from being absorbed into Lylat. Wait a minute did I just screw up somewhere. Ok the Lylat system doesn't exist then the new world does not exist, but who would play the role of Sera and combine with Serph to create Seraph to kill God. Maybe Krystal could be Sera, and Fox could be Serph and God could be... Shoots head.
Sorry if no one gets the reference, but that is how screwed up the storyline of DDS is, but it is a fun RPG which anyone who played Persona 3 or 4 should play.
