Can anyone recommend a space themed soloable game for me?

Hello,

I am looking for a spaced themed game to round up my collection of Gloomhaven JOTL and Marvel Champions to play during the Xmas break. It can be anything, from a print to play to a bigger board game. I already looked into Xia (would be perfect, but out of stock), SW:Outer Rim (not sold on it based on a playthrough video compared to the cost of the base game and the expansion) and Spacers (too simplistic and expensive). I am in the UK, so would need something which I can buy here. Thanks in advance everyone. :)
