As highly unlikely as it would be to see this series come to PC as a whole if ever it was considered then the Master Chief Collection would be perfect and I would buy the shit out of it. Maybe Microsoft might consider it if Windows 10 comes out and if the collection was exclusive to 10 that would be huge incentive for people to buy the OS.
Far Cry 3 on it's first day of release for PC had a real bad frame rate on the highest settings but totally smooth on the second highest settings but it wasn't long till that was all alleviated. I will at least wait a bit for Far Cry 4 to get a good patch and the VGA drivers to improve as well.
Well in Chris Schlerf's defense not even the Nolan brothers would be able to write a good enough story for such a bland protagonist as the Master Chief but for me Halo has always been the locations and skirmishes than any dialogue spoken. Mass Effect Might be more up Chris's alley.
