There's a lot of shooters and racers out because people tend to buy those more than other games so that's a trend that probably won't change... But yeah FFX was a great game and of course KOTOR will be around for a long time. And the new Final Fantasy will be released for the PS3 and Xbox 360. I'm not too excited anyway because I think FF12 was a cakewalk compared to FF10.
For PS3 a good game to invest in is LittleBigPlanet because is's really good and it'll have you up all night(seriously all night). And Fable is great for the 360 and will be the last RPG out for a while. And the Wii is full of fun games so there's really no point in mentioning that. There's always Guitar Hero though!
I still think that Sonic the Hedgehog for Genesis is one of the best games ever. I still play it every now and then.
