I must agree, Ruse looks impressive and really tempting, but I'll hold on my promise not to give any cent to Ubi Soft anymore.
The only reason I can see a video game not working because of mis-matched dates is because of DRM, there is no - and neither should there be, any reason why a game should be dependent on any date.
Which leaves me pondering of Ubi Soft's move to enforce online connection to play their latest games. Yes, this is a sidenote, but it seems eye-opening of potential issues and customer relations for this DRM model.
