Everyone I knew loved it at the time, thanks to the Co-op. I don't know if its as fun for multiple side by side playthroughs as the other dooms though.

Having finished it a couple of days ago, I can tell it is absolutely not.  Don't get me wrong, it is still a hell (hurrdurr) of a game and holds up remarkably well in several areas, but it's a totally different kind of experience.  
I enjoyed it, and appreciated it for what it did and what it was, but it is undoubtedly my least favourite of the main series of Doom games.  I'm not sure at all how any of them will hold up next to Doom Eternal though.
Shit looks dope.
