...which has various tilesets, a character generator, popular plugins (like the Yanfly system for RPG Maker), and the like.  It's one of the bigger hurdles of me getting started with Solarus, how to create the assets.  Scripting and using the editor would be easy for me to do with little fuss.

Thanks in advance and please pardon this noobie question.
