Dirt 2 - normally US $39.99
PC Game Download only.
Metacritic score 89 out of 100
This is the steam weekend deal - 50% off. Cheapest I've seen for this game so far.
I was very surprised this wasn't posted already… 'Until Monday' US time so only a few hours left.
Warning BIG download - 10.05 GB
Special is now Expired
Regarding the BIG download, a lot of ISP's have Steam unmetered from certain servers…
You can limit your download to said servers by first installing and starting up either Frey's Steam Filter or Steamwatch applications (Frey's is said to be the more reliable of the 2), before starting Steam.
