Once you start, you'll be spending a solid 2 weeks non-stop in this game. Lots of imagination isn't required either thanks to the workshop. Projectors (in game) are VERY useful for survival!

It's $0.99, and looks kinda cool. Like Space Engine but literally just for a black hole. Could be useful for a classroom setting or just a background while you do something else!

Another gem hidden from view, wrench is the younger, prettier, more fun sister of Car Mechanic Simulator. The game has a unfathomable depth to it that will leave you playing for weeks at a time.

A gem hidden in the dark. Helium rain is a much more casual and laid back end of X4 or X3. Quality trade system and fun management, it's well worth the small price to give it a go.

Not quite as in depth as terraria, but also not nearly as time demanding. Very easy to casually pickup and play while still retaining it's depth and unique playability.

Worth every penny. There's so much content and things to achieve, the progression system just scratches the surface. Best played going in completely blind.

It's a unique blend of assassin's creed and colony management. Just as a hint... don't get too attached to your orcs...

Capitalism means science fiction. Coupled with amazing physics and to-die-for gameplay, this game blows MANY early access titles out of the water with sheer simulation alone. Well worth the money.

It's like Planetary Annihalation had a baby with Factorio, and that baby decided to become a Physicist. You'll find your time slowly being eaten away without realizing it, which is the best feeling!

There are very few games that can teach you real life skills. There are even fewer that can teach you rocket science in a fun and engaging way. KSP is just something that everyone should try!
