Top Selling Video Games

What are the top 5 selling PC Games in the last 2 years?

IM doing research for a project for school and I need some help finding out what the top 5 PC Games for the last two years are, what the total sales for each game were for each year, and what the share of market was? Can anyone help me with finding this information?

1. well...thats kinda hard since we're about half way through this year, try just 2007 and 2008 cuz of dat
2. Well all i know is that Left 4 dead has to be one for. call of duty 4 Team fortress 2 call of duty waw and WoW
3. Here is the Top 20 for 2008: http://pc.ign.com/articles/945/945328p1.html Just look at the top five if that's all you want. Top 10 2007: http://www.firingsquad.com/news/newsarticle.asp?searchid=19264 And a fuzzy list for 2009, so far: http://giantrealm.gameriot.com/gaming/best-selling-console-and-pc-games-so-far-in-2009 Just scroll down, down, down to the PC section. Note that digital sales like Steam, EA Store, Impulse, and Direct2Drive aren't tallied by the NPD. So it's a very fuzzy and most likely inaccurate list. Your random guesses are meaningless. NPD data and whatever numbers Valve release for Steam sales are all that matter.
4. from what i seen the best selling pc games were asassins creed, left 4 dead, gears of war, crysis and mass effect(and the sims 2 and 3 but you can't call thoose games). i didn't put he games in order but i hope it helps you
