Quirky in a "it's so bad it's good" kind of way. I've had no problems with getting disconnected or finding legit servers to play on. But I suppose mileage will vary with use etc.
Even with a few games under my belt I've realized very quickly that it's got more quirk than I can handle. It's not a game I'll put any more time into.
I'll stick with watching jacksepticeye's gameplay for both in game action and fun commentary.
