You are right, SQ42 can be a nice looking flop if the gameplay is bad.
But for what I've seen from AI in SC when the server is brand new and from some missions in game, I doubt that SQ42 will be a flop.
Statistically though they have failed to release one single game.
That's a 100% failure rate. That's not even opinion. No released games since 2012.
It takes a heck of alot of crunch to release a game, the amount of games that have casually meandered into release state with no crunch is none. The best industry talent they hired have since left and they constantly say it's "two years away" like they think the general public are foolish.
