Pokemon Black and White focused on exploration and player choice. Even though you can't do the gyms out of order, you can travel the Unova region whenever you want. TMs, HMs, and EXP are fixed as well. Black and White and its sequels have more content in them than basically any other Pokemon game, a fantastic soundtrack, and an amazing level of player choice that made it stand out.
