One game I love is Pokémon (all of the main series RPGs, but my favorite ever is HGSS). These games follow a few major parallel interaction arcs — for example, earn all gym badges and defeat the Pokemon league and defeat the evil team (in the case of HGSS, Team Rocket). There are smaller sub interaction arcs such as catching the Farfetch’d or delivering the running shoes or getting the elixir for Ampharos. Finally, there are interaction loops such as defeating gyms and navigating to the next city. At the same time the player undergoes even higher frequency interaction loops like catching Pokémon and battling other trainers.
