Hi Aaron,
My class dipped their toes in minetest recently: Christmas Challenge 1 – Minetest – Banton Biggies.
Setting up a local server was really simple. I managed to get the class having a little fun without really knowing much. These types of games are always a bit daunting for non-gamers like myself but the low entry barrier means I can tread carefully. I’d be interested to see what other schools are doing with minetest and the similarities and differences with minecraft.
