I'm talking about the Nuzlocke run, which is best explained, like most things, by Dorkly. This challenge is basically going against the whole spirit of the game.In what way?
The system is strong. The content does not properly utilize the system.So, I'd say what makes turn-based battles fun is when the content and encounters properly showcase the fun in the systems. Neither exists in isolation, and blundering one can render the other irrelevant to most of your audience.
I mean by find the bad part, you'll know how to make the game more fun.Goodness me, that goes against my principle, flaw-finding opposed to enjoyment-finding!
