please no starforce. Since the game will have a multi player aspect you can use an ordinary key. When some one with a false key logs in on the servers you can block the game and his account. Use steam, force internet connections to play the game anything but starforce.
I've gotten another starforce game (trackmania sunrise) and it won't work on my xp 64 bit (haven't tried <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> on xp64 (checked the faq nope it doesn't)). Lucky I have a dual boot system.
Not in the mood for cheese? That excuse has more holes than a slice this fine Gorgombert!
