Each sport handles it on it is personal.

Often these video games will increase the XP wanted by every stage, and that is normally dealt with by some form of algorithm, however that algorithm varies for every sport, as every sport progresses at a unique tempo.

Such Algorithm will be so simple as e.g. XPNeeded = 100 * 1.2 * stage, however will be extra complicated relying how briskly you need to stage up early, and the way massive you need to scale it at bigger ranges.

For a singular instance of a sport that solved it by itself: Paper Mario.
This sport saved the XP wanted the identical, however lowers the XP achieve as you stage. At some level, weaker enemies do not give XP in any respect.
The enemies I’m that sport did not have ranges, however these have been primarily based on when and the place they seem on the earth.
