Paper RPG Maker on Steam is also totally free for non-commercial projects. You can use it for free until you decide you want to market and sell your game. It's basically all the simplicity of RPG Maker except free. If you learn RPG maker (and if you haven't yet, why not? It's probably the absolutely easiest place to learn basic game development in my opinion) then you'll find the interface and engine is almost identical. It also does that Paper-Mario-Esque 2.5D RPG thing really well and, well, that's a big awesome free feature that hasn't run out of novelty or cool factor yet
