This 2d sandbox game is actually quite interesting it has a lot of similar details to minecraft but at this point I declare this an independent game.

Portal was and still is a groundbreaking game where you take place inside a place and you must use the power of the portal gun to get around and escape

This sandbox brings you into multiple types of games made by the community for the community so definitely a game to pick up.

A fun strategy game where you control an entire nation from war to food.This is also great because server members found out how to do multiplayer mods.

It's a team based shooter game that is really for the fun and not competitive aspect,plus it's free.
