This is an example of a well designed games site. Note the simple and functional (yet attractive) layout, the use of only 3 text colours all of which contrast well rather than being chosen almost at random, and so on.
No competent interface designer would ever use 5 or 6 different colours of text.
edit:
http://www.planetunreal.com/ is a simlar layout but with a different colours (although again note the number of different colours used).
http://www.planetdreamcast.com/ is also quite nice although I dont really like the orangey colour.
http://www.ccgr.org/ (lol) is another fairly attractive minimalist games site, although the text is too small and the centre panel seems a bit wide.
www.gamespot.com is an example of a terribly designed site. Its unpleasant to look at compared to the above because there is far too much going on - the navigation system is also a joke.
http://www.gamesradar.com/ is bad for similar reasons, and look at how ugly the massive unused space on the right looks, compared to the above sites which manage to use the whole screen area well. Just because youre making a website devoted to a fun topic, it doesnt mean you should randomly throw in lots of pretty pictures and colours in the hope that something nice will emerge.
