So, after I had a horrible experience trying to buy the game, I got it all downloaded and started playing it. There are a few things it needs to have any sort of staying power:
1) More inventory. I can barely hold enough carbon to walk around more than half a kilometer in my highly toxic world, much less collect all the stuff I need to repair my spaceship.
2) Something real to build. Without a project to work on, the game will get old quick...instead of a sandbox, this is a kiddie pool...you can splash around for a while, but without having the ability to meaningfully alter the world, it gets old and repetitive.
I do not feel I wasted money on it...there is a lot of potential here, and the scale of the game is incredible. I hope that the innovations are put to good use in the future...if so, my money will be well spent. And hopefully I will figure out how to build a hyperdrive at some point and maybe get some dog-fighting out of it.
