ARK is feature-complete enough, and stable enough, that if they never finish it, I'll be happy with what they've got out now. Except that's not what's happening; there's at least a patch a day (making running a server a pain in the ass). They're adding content at a nearly impossible pace, fixing weird issues and adding community-requested features all over the place. The only thing wrong so far is framerate, it requires some pretty beefy hardware to run KIND OF smoothly. You won't get 60/1080p out of it no matter what you throw at it, but you can probably squeeze 40 out. Unlike most EA games, you can SEE where the performance went.
Anyway, point is, it's earning that 10million. It's a fun, if slower paced, game to play with your friends. Planning excursions to start at dawn so you can get back safely before night, with a few resource-laden dinos in tow, is a neat change of pace. Night still comes on too fast, by the time the sun looks like it's setting, you have approximately 30 seconds before nightfall. You do NOT want to be out at night, as you can EITHER carry a torch, or a weapon. Not like a weapon's going to help when you hear trees falling and a bellow...those moments are truly terrifying and awesome. We have our own PvE server going, as the douchebaggery going on the public pvp servers is more than we want to deal with. The various dinos are providing JUST the right amount of failure-to-success for an enjoyable way to spend an evening.
