It’s hard to say when you “finish” a procedurally generated game like this, so I’m going with “When I promoted a class and beat a Deep Dive”.

DRG is a great game. It’s buggy as all hell at times, but has some of the best emergent cooperative gameplay in anything I’ve played in years. And the bugs are endearing. Easily worth the $30. Definitely worth it once you can reliably load into a game without someone’s boot cosmetic blotting out the sky with graphical glitches.

As with a lot of games like this, how good it is is entirely dependent on having a dedicated crew to play with. I’ve got that, so it’s great. Your mileage may vary.
