One word: Classic. This is, in my opinion, one of the best made Pokémon
games I've played (and I've played a lot, mind you). While the
graphics aren't perfection, the game definitely makes up for it with
the revolutionary changes it made. One example is the introduction
of moving sprites. The storyline is great, the characters that are
thrown in make the story even more interestingly detailed. There is
also additional side quests within, such as the Battle Tower and the
Unknown side quest, which was previously unavailable in Gold and
Silver. With all the numerous improvements made from Gold and
Silver, Crystal still keeps the great elements introduced into
Generation II. For example, the day and night function, the
Pokégear, and others. The addition of the Kanto region is especially
great because it expands the journey even more with an additional
storyline that is almost, if not the same length as Red and Blue's
story lines, so it's almost like two games in one. Overall, the game gets
a 10/10 from me. This game brought back memories and great times from the past,
and I hope you get as much enjoyment out of this game as I did and still do.

Nice review. I really liked the poke gear too. I must of spent half of my time playing it in there!
