Characters, attributes, races, and classes.

After all, humans are remarkably modest creatures. You can only find phrases like "the pinnacle of creation" in the works of romantic poets. Game developers would more likely call humans a "starting point." Meaning, an absolute mediocrity, a middle ground, neither fish nor fowl, or, finally, a well-rounded personality. A little bit of everything, and nothing outstanding. In general, as usual.
Elves are terrible bodybuilders (for every point of endurance, you have to give up two bonus points; we talked about bonus points in the "Building a Team" section), but their accuracy is top-notch. Each bonus point increases accuracy by two.
Dwarves, on the other hand, are pleasantly rounded and stable. Including resistance to external influences. Endurance increases by 2 for each bonus point, but magic... Two bonus points for increasing magic by one completely discourages including a dwarf illusionist in the team.
Half-orcs. They have strength, and they are also quite intelligent, but they are a little thoughtful. Strength increases twice as easily, and speed twice as difficult, compared to humans.
