Yes! I've been waiting for this forever. The first time I ran Minetest on a crappy laptop years ago it was as smooth as butter and I couldn't help but think, "Why is no one playing this?!"
I think the primary reason very few people play Minetest is because of marketing and piss poor default gameplay. If you just run Minetest without adding any of the (nearly built-in) mods you'll get an odd-looking Minecraft-like world stuck in "creative mode" (which is boring). If, however, you take the time (lots of time) to fiddle around with it and put together a collection of decent mods it becomes a good game!
The fact that it is written in C and has a proper modding API (in Lua!) should be drawing people in like crazy but for some reason it isn't.
