Ranked in these QuestionsQuestion Ranking
Pros
Pro Easily customization through LUA mods
An easy to use lua API, and a large variety of existing modifications and games that can be downloaded and installed easily.
Pro Open Source
Pro Runs fast and clean
Runs on Low-End Hardware, runs Fast, Spartan on Memory.
Pro Cross platform

Pro Fewer griefers than Minecraft
The smaller community means fewer players, and that mean fewer griefers than on Minecraft.
Pro Built for plugins from the beginning
Pro It's Free
Pro Fun and thorough tutorial
There is a tutorial game that you can download that teaches you how to play Minetest in a fun and intuitive way. There are even collectable gems you can try to find in the tutorial.
Pro Endless solutions
With proper planning, users can "code" together very precise ways to create all the things needed for the game, some in very inventive ways that can differ quite a bit. This allows for tons of replayability.
Pro Under active development
The game is still in Alpha which means endless future possibilities.
Pro Massive and infinite procedurally generated world
The playing world is as large as you want to explore, it automatically generates it as you explore more areas.
Pro Cooperative or PvP building
Factorio also supports multiplayer, allowing many players to cooperate and assist each other, or work against each other in PvP. By default, multiplayer games run the CO-OP freeplay scenario where all players work together to launch a rocket with a satellite into space.
Pro Charming old school graphics
While not the most technically advanced graphics the look of the game is much like a game from the 90s but seeing it in action when an assembly line starts moving there is an impressiveness to it that suits the game quite well.
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.
Con Cannot be played on the Raspberry Pi
Con Can become rather repetitive
There's really little payoff for being able to build really long chains of automation, it usually results in being able to open a new tech tree which allows the player to continue the process of building automation chains ad infinitum, which, admittedly can become rather boring after a while.
Con Still in Early Access
The game is still in Early Access which means there will be bugs as well as missing features.
