Why not use Windows Experience Index as another guide for game selection?
First post but serious question. Before spending hours downloading a game only to discover my laptop won't run it, I was wondering whether Steam could use the WEI as a guide for potential buyers. Even with the "Minimum and recommended requirements" it might be easier just to say "don't bother if your WEI is under 5" (or something like that). Anyway - it's just a thought from an old man who doesn't undertand technology but loves to play games. I'm happy to be corrected if my suggestion makes no sense or has no chance of working.
