Relatively lightweight, a lot of options to fix that, if it isn't. Made with Java, guaranteed multi-platform with few issues. The main point of the game is the options, there are so many things to do and to discover, and it works flawlessly, despite its being still in development, and things get added en mass with every update. Rich man's Cataclysm: DDA, one could say. More in the graphics aspect, rather than the mechanics, but it looks like these developers are working on that.
