King Arthur's Gold (KAG for short) is a side-scrolling RTS type of small indie game based on the elements of Medieval Europe theme. It came up with retro & pixel style and unique, rare originality, and of course got inspiration primarily from one old video game King Arthur's World on SNES platform.

Universe Sandbox is a very cool software designed to simulate the physical interaction movements (you can create & destroy on an unimaginable scale) of universe stars perfectly. It has a 3D engine with very high simulation degree, and is a pretty darned good simulator (also can be regarded as a scientific game) for understanding the whole universe.
Planet Centauri is a pixel-style sandbox based indie adventure RPG game with very high degree of freedom. The game content is roughly the same as Terraria and Starbound, but its global style of graphics is more downy.
Terraria is a popularity pixel-style indie game nicknamed the 2D side-scrolling edition of the famous sandbox game Minecraft, which was launched on PC in as early as 2011.

Of course, it's really as fascinating as Minecraft.
