Smile Game Builder
Others via Unity
Smile Game Builder is a piece of software targeted at making 3-D, Japanese-style RPGs. It seems to be as easy to use as RPG Maker, but has some cool additions like a character builder. Updates and add-ons are still being released.
It's Windows-only, but there's a (n expensive) add-on / DLC pack that let's you export to Unity. From there it's apparantly tricky to make changes, but easy enough to export to any platform Unity supports.
