Mods

Mods is the best developed additions to bring more interest to minecraft. There are millions of mods that was helpful. But one worst thing, If you get much mods, you minecraft lags. Sometimes lag even made minecraft freeze.

This is nice and bad diagramm.

Pros
-Very interesting. -Brings more blocks, technics and new monsters. -Makes gameplay easier or harder. -Works fine.

Cons
-Lags if many mods active. -Some particles go wrong in lag and cause worst details. -Monsters don't render their body parts after much lag. -Minecraft freezes, killing your spent time on mines. -Some mods may not be for your version. -After 80+ mods active, minecraft is crazy maniac.

Don't get mods too overpowered or become a headache.
