Any STEM school teachers using video games?

Hello everyone!

I'm buinding a free browser based educational video game for school students which gives them fun and allows to reinforce math concepts.

I’m curious if anyone here uses video games or game-based activities for STEM enrichment, especially with grades 1-5.

Things like:

-Minecraft
-game-based learning
-simulations
-educational games, etc.

If you’re using anything like this, I’d love to hear what is your experience with it. Pros and cons.
What do you look for when it comes to bringing a new "game" into the classroom?
