i dont think its a good engine, it limits how you make characters (rpg maker and others dont), 3d battle system is ff7 style but no one can change it to make it new/ 2d battle system is the same but oddly place characters, exporting to unity can be a downside for people who do not have super computers/good specs, creating multi-language text looks hard and lastly it is only steam with DLC lock features; it is not just me but anyone who relies too much on steam can expect bad stuff to happen to their game just like many engines that update before it.
again dont think this engine has anything for people who want to customize it, the engine might not work for some with lower spec computers. i wouldn't want my characters or world to look like minecraft and to make them human like seen in some games/videos requires 3d modeling instead of grabbing it from the internet then doing small modification.
