At best this program makes reselling the game more difficult, and makes running the game in an internet cafe more difficult. For people who want to give it to 10 of their friends I have no doubt that they will wait for a crack and it will be here very shortly.
@Tumbler - good point. Maybe the 2 install aspect is a bit short sighted and over eager in that current implementation. But I don't know a better solution that wouldn't be more intrusive. Maybe they should have allowed mass repeated installs or maybe more like 3-5 to avoid potential issues down the road (especially since cafe's aren't going to be a serious problem without MP). The inconvenience could be a real one for some people or just wipe a drive, which would include me. So modifying the limit of 2 installs will likely change in future Securom iterations.
I actually would not be surprised if 2K will remove Securom eventually in a patch (including the online component 2 install check down the road), like many companies do, after they hit the sales decline in a couple/few months.
