Giving the player multiple things to keep track of also increases the pace, you want the player to quickly jump back and forth between different tasks. E.g. all of your character take turns individually, so you need to jump around and give everyone orders as quickly as possible (maybe even strategically give someone longer spellcasting orders so they keep busy for a while, letting you micromanage someone else for a while). Try booting up multiple instances of the same RPG and alt-tab between them I have a friend that actually does this and then figure out ways your game could be that, but canonical.
