Yep. I'm also really thankful for every demo I can play before buying. It's the same with the steam next fest, which is completely dedicated to demos games :D Some games I won't have bought, if I weren't able to play the demo beforehands :-)

I recently discovered Stardeus which is like a Rimworld in Space game, where you are an A.I. on a destroyed spaceship with a few bots and you try to repair the ship and try to keep the humans alive. If you want to. You can also just kill them and create a bot empire. It's more layed back than Rimworld in my opinion, which is a good thing for me. Oh and there is a demo that you can try before buying it!
