Symphony X! Haven't been into them in a good while haha, but I loved them years ago. How about Blind Guardian?
Looks promising, although I wish they were making a big campaign too. Wolfenstein The New Order was also amazing, then Doom, so they were on a roll... I bet a new Quake campaign could have been epic. I like Quake 2 a lot, but it would have been interesting if they could have taken Quake back to its neo gothic sci-fi roots like the first one, which seems to be Champions. But it's multiplayer only...
I didn't like Wolfenstein The Old Blood that much, but there's been a lot of rumors that they're working on a sequel to The New Order.
