if implementing this as template would take very much time, i think u can do this as an example or demo (based on another template) and sell it as a dlc, but if u prefer creating as template, my suggestion is a platformer/side-scroller one (cuz it looks like the platformer template we don’t have a new one for it like enhanced rpg)
client/server mutiplay dlc with join/host lobby style
We now have the MMORPG Kit you can use for that, as well as a P2P demo showing networking capabilities.
