If I am buying a console I know why I am buying it. I know some games I want definetly to play. My question is why did you bought a PS3 ? Isnt a 360 or a WII more appealing to you ?
To Controls I never had a problem with Controls in a PS3 Game they work more then perfect for me. I think accessable controls have Uncharted 1-2 Killzone 2 Lost Planet 2 .... if I think about it pretty much every PS3 Game I got, I saw the Layout which button which Action and I started to play without problems even without thinking about it.
You should buy a WII or wait for the PS3 mote which will be pretty much the same thing.
And if I were you I would buy me a nextime a console after I knew that the games appeal to me.
Edit: Sega want to release some old Sega Games on PSN. The problem is Sega is not as good as it was in former times. Atleast thats my opinion. I loved the DC even the Saturn was a good console in my eyes mainly because the Controller was good for Beat em Ups and Sega hat definetly a Edge over PS in the beginning.
But inuitive Controls ? The DC Controller Hurt my thumb pretty much. The Controls were never an advantage in my eyes. If you liked Sega that much and you want good graphics then PS3 is maybe the best decision. FF 13 FF vs 13, Yakuza 3 and 4, Resonance of Fate. Didnt released Sega Nights on PS3 or was that on WII ? Phantasy Star and Sega want to release all former Games on PSN hopefully ShenMue 1-2 and maybe a successor. But as I know Sega they try to make money of their old Big Hits best axample Sonic maybe they will make a successor to Panzer Dragoon Saga on PS3 ?
