I've been working on a little 2D Rpg Map Editor and it seem like it's doing well
The engine behind this is Unity.
check out the package there : Unity Package
20$ give you access to a very high detailed tiles, also got more than 4000+ PNG for characters with all parts needed.
Just try the demo, you'll see how powerfull it is Demo
Currently, only the character and tiles Editor has been done, but I want to code also Turn Based fight (just like Final Fantasy), Custom Event which doesn't require coding skill, Dialog system, NPC AI... and so on
If you have any question, send me a email to firstname.lastname@example.org
Here is some screenshots
