It's new in the sense it's the engine fallout 4 is being run on and while it's a heavily modified version of Skyrim Engine, that engine wasn't not all Gamebryo, gamebryo was only a small part in the original skyrim and even less so in fallout 4. It's only in the engine so the mod support can be as easy as their games always allowed. THAT's why gamebryo will likely never go away because the modding is the biggest thing people like about their games. So it's loosely a new engine but we all know the PC version is much better usually than consoles.
Don't get me wrong I LIKED the additions in the wasteland workshop but there's NO reason for there to be two more wasteland workshops in being done. There should have been 1(even then it's questionable) Wasteland workshop, 1 more Automatron like DLC and Another $24 DLC.
As far as your comment about dlc: Fallout New Vegas for all it's negatives for the base game had 4 areas that were fully explorable with new areas. Lonesome Road, Old World Blues and Honest Hearts had it's own map, 15+ locations and good story as well that tied well into the main characters like NCR and Caesar Legions.
Fallout 3 DLC's were good but not that great. New Vegas had solid DLC's because the main story was crap. And here with fallout 4: we're now being concerned that the $49 season pass is now a complete waste because 2 WW and Nuka-World where there's no indication it's a $20+ expansion is messed up. People who had the PC version when Far Harbor update happened saw those two dlc's and figured out Nuka is not going to be a big dlc, hence why I'm saying it's complete bull and bethesda screwed up. There shouldn't be 2 wasteland workshop dlc's. We want storyline dlc's after the success of far harbor why the hell would they make 1 or 2 more of those? I'd rather have 3 $10 expansions ala new vegas style than what we're getting. Luckily I only paid $30 for the SP but i'm not going to pretend that those new ones are a good deal.
You're serious? Resident Evil 7 announced? Damn, I was hoping they wouldn't make one until RE2, 3 and possibly CVX was remade.
