Nope, nope, nope, nope, nope, not gonna happen, not gonna happen, not gonna happen.
Thanks for the persuasive argument and well thought out response......
If only. Sadly, even if one is made, it's not the same people so will not be a true PGR
RTW said they won't work with MS on Crackdown again and Ruffian Games are making a PC title, confirming they're not working on Crackdown 3. Many of the complaints over 2 were because of Ruffian so I'm not sure MS would chance it for a 3rd developer.
Totally wishful thinking I know, but another PGR could still be amazing if done right. Codemasters maybe?
As for another Crackdown, even if MS wanted RTW they closed their doors years ago, and they wouldn't risk Ruffian again. So they would have to chance a 3rd dev if they are serious about continuing the series.
