I think it's hard for most of us to make any suggestions about this stuff because we don't know how everything's gonna link up with this new VGR thing. If NintendoXtreme is going to be included in that then the name will probably be dependant on how VGR works. If there's a load of forums called stuff like '3DO Rebirth' and 'Neo Geo Rebirth' this place is going to have to conform to that (like I say, if it's included).
Apart from that, maybe you could base it all on bad wordplay (news would be 'Nintendossier', exit would be 'Nintendoor', bad game would be 'NintenD.O.A' etc.).
OK, maybe not..
