It has not aged well. But at the time was amazing.

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.)

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.
