Dust 515

Lol even. But to be fair I don't recall Dust 514 actually being bad, just very poorly timed.

especially if the FPS gameplay made a difference to the overall game in a significant way

I don't know if you've ever played EVE but I can tell you how that goes:

1. "Fuck CCP for spending resources on a fucking toy FPS instead of real content and fixing bugs."
2. "And now it's impacting our economy."
3. "Yeah! What do we blockade to make the FPS unplayable?"

Edit: I wonder if this is actually a reaction to Star Citizen.
