gamasutra has a list of the top pc games of 2005 by sales.  as has been the case for like 20 years now, way too many people are buying the sims and its expansions.  one of these days will wright is going to be spotted sporting ridiculous gold chains and diamond teeth.  it's just a matter of time until he loses control with all that money.  :) 

also on the list at #4 is a game called guild wars.  hmm that sounds interesting...  maybe i'll go buy a copy (or twelve) of that one!
