Loving the power and simplicity of the plugin... Amazing work,!
I'm currently working on a Fate Core implementation in RMMV and very much seeing this as the heart of my skills systems.
So essentially every skill would be 0 and you can level up according to a scale, starting with 20 points that can apply in the order of-
1x 4 point skill [ ]
2x 3 point skill [ ] [ ]
3x 2 point skill [ ] [ ] [ ]
4x 1 point skill [ ] [ ] [ ] [ ]
You'd only be able to level up a skill if there a supporting level beneath it, so your next upgrade would be either a 5th 1 point skill, a 4th 2 point skill, a third 3 point skill, or a 2nd 5 point skill, provided you had adequate points.
Has anyone else looked at doing something along these lines?
