RIP for the days of each new version of a game having significant advances and not just a reskin/rehash/new story version of the same thing on nearly the same engine.
Thinking Commander Keen → Wolfenstein 3D → Doom → Quake kind of things.
(Sure there were always expansion packs or similar, but often done by other studios and more of a primitive DLC (Doom II, etc). But Warcraft → Warcraft 2 → Starcraft → Warcraft III was way more of a jump than the various Halos, say.)
The second one didn't sell well as a result of being scheduled for release on top of a Call of Duty and a Battlefield.
Reportedly it was an effort to suppress Call of Duty sales but en effect basically sacrificed Titanfall. Respawn management were very, very unhappy about this.
It's a shame, it was a great game with a fantastic campaign. I have a few hundred hours in the multiplayer too.
Dead Space was an amazing Action/Horror trilogy that had a brief comeback two years ago with a remake of the first game that was superb but apparently underperformed sales wise. The studio that worked on that remake (EA Motive) is still around and working on projects so there’s still some hope of a Dead Space 2 Remake.
