I bought into Edge of Space by itself a while back, and was disappointed with it. Was expecting a broader path of development, but my experience was fraught with frustration. Weapons were weak compared to enemies and I couldn't even figure how to get better armor to survive the environment (there was a sort of "drowning/oxygen" system) let alone the more dangerous enemies at deeper depths. The UI itself was also frustrating to use, there were a lot of annoyances that I presume were getting backburnered in preference for more content development, waiting to do a passover on UI usability once the game is closer to to complete. (This is a mistake, in my opinion: any playable open beta should have a robust, functional UI, even if content itself isn't complete.)
I decided to put it aside and wait for it to be finished, barely hoping it might turn out decent then. But that was months and months ago, no idea how far along they've come since then.
I might pick up the bundle anyway, though. Reassembly looks very interesting. I am extremely uncreative (especially in 3D environments like Minecraft and Starmade) but the 2D aspect may be simple enough for me to work in. It looks like a more freeform S.P.A.Z. with a broader scope, which intrigues me.
