Hello dude,
It depends, if you do have a component cable, even European games will work on your 29" SDTV, but if you're using a standard video cable, you will only be able to play American and Japanese games. That's due to a difference in horizontal resolution between Euro and USA SDTV standards.
So you got two options: Buy a component cable ( they're quite cheap ), or buy a HDTV and a HDMI cable. Problem solved.
