What happens, when the non smart microwave finally breaks and only smart ones are being sold? You could buy used, but what happens when that used inventory is used up?
Fortunately in case of microwaves, the simpler ones have the same internal parts as smart ones, and as such some supply is most likely going to be available.
When I did play foss games, I played battle for wesnoth, teeworlds, minetest, super tux csrt and openarena. Lsst one might be dead due to being a mainly multiplayer game.
