An excellent multiplayer game with a forgettable singleplayer campaign
I'll go more in-depth with the campaign below, but I'll summarize my overall impression of the game first. Buy it for the multiplayer. The campaign provides a short but fun couple of hours, though you probably won't remember it in a year. The multiplayer, however, provides a much more memorable experience. The dedicated, albeit small, playerbase is testament to that.
Okay, so the singleplayer. In terms of customization, Academy succeeds. You get to pick your species/gender/lightsaber from the start. Also, aside from the main narrative driving levels, you're free to pick or ignore missions at your leisure.
Unfortunately, no amount of visual flair breathes life into the main cast. Kyle Katarn and Luke Skywalker make their returns, but only sporadically. Instead, you plays as one of many new students at the Jedi Academy on Yavin 4. As interesting as that sounds, there just isn't a real spark to this game. The story plays out as another macguffin hunt and foiled attempt at resurrecting an ancient evil. The dialog is about as strong as the prequel trilogy's, in terms of tropes.
I could critique the narrative structure forever, but you get the point. So ignore it, and just have fun wielding a lightsaber and throwing force powers around. The spontaneous, awesome moments of fighting squads of stormtroopers, or groups of sith-wannabe's make up for any faults.
