Well.. those 8-bit and 16-bit nostalgic games don't appeal for me.. I had a Atari2600 when all people was playing NEs or SNES.. then I switched to PSX.. so I can't feel nostalgic of games from those ages...
and about RE: REV.. Yeah.. CRAPcom is a b*tch.. and is probable the "not other handheld release" agreetment with Nintendo, if not I can't think of any reason to leave that game out of Vita...
