Cons
Con Lack of mobs
Yet mobs can be installed through mods or subgames. However, if the server is not optimized, these can make the game run slower.
Con Not much to do even with mods
All I do in the game is dig underground and mine the ore within the caves. There are no monsters to fight, dungeons to explore, or any leveling systems/progression mechanics to keep me playing.
Con No weather
There's no built-in weather. However, there are mods which add this feature and extend it far beyond what you might expect from basic weather.
Con Rips off Minecraft
And not very well either.
Con Certain graphics are really bad
Parts of the games's graphics and functionality are really bad. Mob mods or default mobs look like a 4 year old drew them. However, the devs seem to be slowly sweeping through these issues. Come back soon if you don't like what you see yet.
Con Server lags
Almost everything is done server side, so the game can feel very janky on some servers.
Con Minecraft mod ecosystem separate from Minetest
Minetest is obviously an opensource implementation of Minecraft but the only problem is all the mods made for Minecraft do not work in Minetest. They could have designed their clone in such a way say fix it at 1.7.10 forge so that you could load up forge mods straight up and have them work somewhat. There's so much great content for Minecraft that is completely lost and unusable in Minetest, however at this pace of developement, maybe that will change in the future.
