 Despite the fact that it was made with Essentials games in mind, there is nothing connected to it contained in this repository, and it should still be compatible with anything that runs in the upstream version of MKXP. You can think of it as MKXP but a bit supercharged --  it should be able to run all but the most demanding of RGSS projects, given a bit of porting work.
