Yeah, the Halo series has been a Microsoft product since it came out. They just released the Master Chief Collection to PC, as well as added Reach to it. It was all certainly a product of it's time and these guys don't really keep up with the modern style of shooters. Definitely going to be a every once and awhile thing for me at most as I found myself very flaccid after playing for a few hours.

The only WW2 shooters I remember playing were the very early COD ones before they had multiplayer. Well, and shit that bopped like Wolfenstein and stuff like that, too.
