I've been playing this game since March 2016. It is, by far, one of the best games I've ever played.
Ever. And it's not even completed yet.
It's being built by a team of four people, and they're constantly doing updates as they work towards a finished product. I enjoyed playing this game last year in March as much as I do right now, and I'm not going to admit to you how many hours I have into it.
When it does come out, it's a big enough game to warrant the full $60 price. So, do yourself a favor. If you have a PC and use Steam, buy this game. Do it. Stop asking questions. Just do it.
Also, make your friends buy it. It has online multiplayer capabilities.
