there was posts from people on the 22nd saying that they were playing with a pirated version.. ONLINE.
so either a bunch of people were lieing or it was 'cracked' or at least had a work around in less then 3 days. not to mention if it wasn't working it is a bit weird that over 20,000 people were downloading it which would be a big waste if it didn't work.
personally i don't mind steam as a mode of copy protection, it's better then most other forms.
BUT.. i did up until recently have a computer for the girlfriends kids that did not have an internet connection, and that would present a problem with playing such games so, even after i purchased some games i would need to use a crack or pirate version anyway.
the best way to keep pirating down is frequent updates!! so pirates will most likely be stuck with an old unpatched version without the added content / fixes of the patches.
