Yep... definitely, buy Rimworld!

I remember playing the original Half Life when it came out! It was mind blowing! I wouldn't go back and try it now, I like my rose-tinted memories... I didn't try the D-day game (I know the one, but the name escapes me...), for quite sometime I got hooked at university into the Counterstrike and Starcraft multiplayer scene... well, if you could Engineering and Science nerds hogging the university network resources a scene...
