I was trying to check the compatibilities but it looks like your page is under construction. Is there another place that someone could view the compatibility list?

The tilesets definitely load in Unity. I don't really know Unity, but I was able to get tiles up and running fairly quickly after a little research, and I could draw a simple map with them in a short timeframe. As for templates, I can't say for 100% certain that I know, but since I used default functions to import the tiles, I'm thinking it's probably fine.
This tileset importer was also recommended to me. So you definitely have some options.
as for unity - we'll (hopefully soon) see a rpg-maker version for it
