You can get excited, but don't get too excited. Yes, Final Fantasy Tactics - The War of the Lions does have multiplayer.

However, multiplayer is not that glamorous in this game. It is basically you fighting another opponent. Unless you know the person that you are playing against, odds are that your party and their party will be so unbalanced that the actual game will be over in seconds and not that much fun really. This game is meant as a single player game. Once you beat it, if you're still bored and want more, then try the multiplayer; not before.
