It is a good piece ofhardware exept for the lack of scaling and definately has potential, but as far as games go the 360 launch was way better. I have full auto 2 and i think it sucks and i have all the arcade games you mentioned and they are pretty weak to and there are better versions on the 360 exept for sudoku.
You are entitled to your opinion and i am glad you are happy with your purchase, but having had the system since launch it has only one good title and that is resistance.
The 360 launched with condemed, call of duty, kameo, perfect dark, quake 4, tony hawk, project gotham and several others. Some of these werent very good but at least there was a choice.
Again, i am glad you are satisfied but as a 600 dollar gaming machine i am not, my hopes are high for the future though.
