i think for me it was nes, then gamegear, then ps1. there was a huge gap between gaming systems, i guess. which about sums up my life. still no ps3! and i only recently got a wii. oh, the joys of being poor.
oh the sony/nintendo publishing thing makes a lot of sense, actually. i hear a lot of drama about eu localization. like smt iv taking well over a year (?) to get an eu release. and even then it ended up being digital only.
