Or, something cool could be added to make travels a bit more interesting (something related to a training minigame???)
I'm a Nintendo fan, and this is nintendo philosophy: everything in game is a game, so even if you are making an rpg, which reason blocks you from making even a sword swing a moment to play interactively? I'm referring to Super Mario RPG for SNES, paper mario for N64 and other GBA, gamecube titles, where hitting a buttoun at the right time doubles the damage "delivered".
When i go out with my bike to make exercise, i rather mountain and open fields, or even city streets to boring state roads.
an example? --AND THIS IS THE SUGGESTION PART--
trasforming some "just numerical" skills like pathfinding (or training) in arcade and therefore "active" parts of the game...
to port another example in GTA S.Andreas, when you use the bike you can speed up by pushing the "forward" button.
Think of it.
