In the game, you play as a main character (who you name, pick the gender of, et cetera) who wants to become a Pokemon trainer. Pokemon HeartGold/SoulSilver is a multifaceted RPG. However, if this is your first Pokemon game, you might be confused as to just what the game's all about, what you're supposed to do in the game, and how the game is ultimately beaten. Those who have played a Pokemon game before won't need to read this section, because the series has changed very little since the 1990's. If you choose to change the controls manually in the game, keep in mind that the control explanations above will thereafter be false.
