... which isn't necessarily bad. RF4 is very arcade as a whole, really cultivating the feeling that you're playing a game. Sprint points allowing you to basically freeze time does fit with that. The only thing about sprint points that feels unambiguously bad is how long it takes for your sprint points to recharge in the late game, if you have a pool of (say) 9SP.
But it got me thinking of a system which would feel less arcade, and more like agility gives your character muscle speed:
* agility (mainly) increases SPregen instead of your maxSP.
To be more specific, you could do it for example like this:
* most characters have no SPregen, only getting new SP from mushrooms
* your SPregen increases by 0.2 per Agility point. (Or maybe 0.1, if that's more balanced.)
* the total SP pool of most characters is 2. Or maybe 1. Rare equipment or talents could perhaps increase this.
* the lava-fueled SP boots and other SP-granting skills could perhaps grant SP beyond the maxSP, but they're lost if they're not used that turn.
This would result in the late game in characters sprinting 1 tile every turn, or 2 tiles every other turn, which would feel more like Agility and less like time magic than the current system. It would also make the Sprint and Jump talent feel more unique.
Even if this turns out to be a bad idea, or if Justin doesn't want to take the game in this direction, I'd be curious to see what a race would do where Agility functions like this.
