Honestly, not yet. ADAM is built for single-screen arcade and platform games right now: things like collect-the-gems, dodge-the-enemies, platformers with levels, and simple shooters. A JRPG needs things ADAM doesn't have yet, such as dialogue boxes, menus, an inventory, turn-based battles and scrolling maps.
I'm adding features all the time, so if there's enough interest in RPG-style tools I'll consider them. Do try the demo to see what it can do today!
Thank you.
