So, it turned out that this was one of the games that Microsoft has made playable on the Xbox One, and as the new Doom is coming out this week (and I am a fan of the franchise from way back) I decided to FINALLY finish off Doom after having never finishing it on my Xbox 360.
All in all, it was pretty much what I expect from a Doom game, but I found myself unfavorably comparing the game to the Dead Space Franchise. One of the nice things about Dead Space is that it has a mission pathing function ... which makes it considerably easier to finish a game when you know where you're supposed to look.
I'm curious to see if the new Doom's demons will look more like the ones from the original game or this remake. Time will tell ... and soon.
But I wish Dead Space would get remastered or rebooted...
