I believe Pokemon Type: Wild was also made using this engine.
I'd imagine that networking capabilities might have had something to do with wanting to do it from scratch. After all, it's a community project, so everyone just wants to play with others from the forum. I did read somewhere that a program called LunaPort allows fighting games made with this engine to be played online (thought it's probably a hassle to set up), so maybe that can alleviate that issue, if this option were to be chosen.
