Thanks again for your thoughts. Your comments have have driven a lot of my rethinking of things. I'm glad the plot and world elements really shine through. I know some people will miss the RPG elements or feel that's vital to the series. If so, they can make any additions they like. Adding mana points is a great example. With that line of thinking, I wanted my skills cut to the core of what MP is: exhaustion. You're limited by how much you can do before you heal or recover. This replicates that by saying: here's some free opportunities you have to influence the plot. But from then on, it's a roll of the dice -- until you heal/recover. But your skills will probably use your best stat anyway. So you should have some good rolls even then, until luck runs out... Bwahahaha
Also, what a "safe rest" is (or how long) can be decided by your table and vary each time. So all of this to say: story comes first. That's what I felt would make for the most fun, succinct system. It's also inspired by the combat changes from FFVII to FFVII: Remake. It sort of takes those to extremes. Example: everyone has a main attack they can use anytime, even if it's with spellcasting, drawing cards, etc.
Another big idea that could be added to the game is Summoning, or more Spells. But perhaps these will come as DLC later. We'll have to see ;) Thanks again for your comments.
