At the game's current state, it's not very fun. On PC, it's buggy and it doesn't run smoothly. I've played it for a few hours, and it's not the worse game ever, it's playable and sometimes enjoyable. But 9 times out 10 I get a crappy, freezing or toxic planet where I'm hiding form the cold or hostiles most the time. I understand it's an exploring game, but exploring planets that have bugger all on them isn't fun. When I get the occasional lush planet, that's got bright and vivid colours, then it's enjoyable to wonder around it!
For what the game is now, I think $60 is a ridiculous price for it. When more updates come in and more features are added then it might be worth it.
