If you're looking to pre-order the PC version of Mafia II, digital retailers are offering a very nice incentive. Any customer who pre-orders the game will get the first Mafia for free.

The offer is now live at both Steam and Direct2Drive. Note that neither service sells Mafia by itself. If you want to hold off on pre-ordering Mafia II and just want to grab the first game, GamersGate sells it for $14.95.

Mafia II arrives in North America on August 24th and in Europe on the 27th. The system requirements for the PC version can be found here.
