Has someone been playing this game? I know the first game in the series was ok. I ve seen the demos on steam and it looks awesome. Which leads to me second question.... I ve got a pretty outdated system: Intel (R) Core (TM)2 Duo CPU E8400 @3.00 GHz 3.00 GHz and 2.00 GB RAM + an ATI Radeon HD 4800 series with 512 MB RAM..... could I be able to run it on min specs (without getting too choppy)?
