Well. If you ask me. Those who say that you must have a plasma TV for your PS3 is lying. Sure it makes the experience better. But it is not needed. I works great with an old CRT TV if you want. Just maybe the graphics arent that good. As for the wii part. I think your old TV can work. As long as it has the AV jack. Mine is like 7 years old? The TV i mean.
