Okay so it is not that far into the depths of time but if you enjoy the chaotic and often very immersive experience of classic games like Spacefarers and Laserburn, you could do worse than check out https://www.wargamevault.com/product/398913/Shoot-People-in-Space from last year.
Shoot People in Space is played with single based figures (individual characters or 3 figure squads) and has a number of built in mechanics to produce unexpected outcomes: Your little soldiers will certainly have a mind all of their own. The rules include points systems, a progression system and options to play against another player or solo. The included units are the usual grab bag of Unified Space characters, easily adaptable to most scifi figure ranges (including actual Laserburn figures if you have any lying around).
So go give it a shot. You may find you have a grand old time.
