Do games look..

Worse on an HDTV?

I remember playing Wii Sports on my SDTV and it not looking so bad. Well now I have an HDTV and I was playing Legend of Zelda, and it looks like an N64 game.

Is it the HDTV, or does Wii Sports really look better than LoZ?

Wii games, yes. especially on LCD.

looks the same, but sharper (the jaggies are more appearent) and stretched out...

get wii component cablesair_wolf_cubed

doesn't matter too much.. it will make the jaggies even sharper, but the colors will be MUCH better.
