Is there a website that will let me compare the same games between different gaming consoles?

I'm debating whether to get a game for a PC or any of the gaming platforms (Wii, DS, PSP etc.) Which one would be a better choice?

Is there a website that will let me compare the same games between different gaming consoles?
For a while, gamespot.com used to give a small paragraph about the differences of each version (i.e. "the Xbox version has better anti-aliasing and cleaner textures, whereas the PS2 version controls better, and the PC version has bugs"). Typically the reviews are pretty much cut %26amp; paste from one system to the other, with that one paragraph difference. However, aside from that one beneficial quality of their reviews, they try to be objective and give great descriptions yet their scoring is inconsistent, and they do succumb to marketing forces (even before the recent firing of one of their senior editors, whether or not it was due to his review).
Reply:not that i know of... but what a great idea for a website.
