It seems like some people never played a game that they like.
That list of games had some really good one on there. To suggest that all the games are just average is pretty cynical, IMO. Why play games if they are so average?
Thief does not look like crap. Granted, the bar has been raised. It is no Far Cry. The polygonal wheels and sprite grass are evidence of that. Most of the rest is really very good though.
I challenge anyone to name better looking games that are out NOW! There are some. Pandora Tomorrow, Far Cry, for instance. But Thief 3 is up there.
