What I think & most people.

I love that the game is very different than other games but I don't like that there isn't an online/co-op mode.I would love to play this game with a friend to expore an alien planet.Thank you for reading

I enjoy the overall idea behind the game and looked forward to it's release on Xbox One. However, in it's current state I feel it's unplayable. The fact that we were given the most basic version of the game to start with, (considering the numerous updates for the PC version to date,) says a lot. Hopefully enough of us have purchased this game to promote future updates.

Unplayable at the moment..

The framerate makes the game horribly annoying to try and play, it also has major issues with loading in the scenery. Often at times im just floating in an empty space with nothing to see around me. Its frustrating because the game looks amazing on the PC. Apart from that im highly anticipating the full release as this could be such a good game in the end. I just hope they fix the FPS problem or I will not be playing this game. Would have given 5 stars if not for that..

Amazing game!

Everything is awesome about it and love the idea for it, my only issue for this was the frames dropping more then it should have and it really needs a co op for it as well. Apart from that i love it.
