very inaccurate.
world of warcraft i can see being number one, if not very high on the list.
however counterstrike (counting both versions) would easily be number 2 or 1, it has about 150,000 to 200,000 people playing online at any given time, so you can imagine how many people actually play total. this versus halo PC maybe 2,000 online at any given time. (

so halo being number 2 on pc? no way in hell. on console; sure. not for pc.
i'd like to know how they got these stats to begin with... going around asking a bunch of console gamers what they play on pc?
