I bought this yesterday along with a couple other Star Wars games, having repeatedly watched the excellent trailer [http://www.youtube.com/watch?v=rsH8LAb-5qQ] included with one of the movies or another in entranced awe as a kid. Though I've only played slightly over two hours thus far, you may as well be aware of the flaws I've been able to notice within that time.
There are a few points where you're liable to die, get revived, and immediately die again because you inexplicably take almost as much time to stand back up as it does for your teammate to actually restore your health. There's not as much weapon variety as I'd like, and your character could do with a slightly faster movement speed (or a sprint function, but to be fair, this was made before those became widespread). A nice feature of your teammates is that they have a preanimated insta-kill move in close quarters where they throw the enemy to the ground and headshot them, but the appeal lessens whenever they do it to an enemy you just used up a lot of ammo on, which is rather often. There's also one useful command where you can order a teammate to take up a sniping position, but there doesn't seem to be a way to select which teammate will do it, and you only have one sniper on your team. Worst of all by far, the game has a nasty habit of infinitely respawning enemies as it waits for you to fulfill an objective that it didn't properly tell you about (a problem exacerbated in cases where those enemies happen to include the airborne, shield-bypassing Geonosians or the heavily armored super battle droids), so get used to surviving through intense firefights only to eventually figure out you've accomplished nothing but wasting more ammo.
And yet, there's something oddly irresistible about the whole experience. I can play any number of games that hand me a gun and tell me to shoot things, but not nearly so many where I can intuitively but extensively direct a squad of fellow soldiers to do the same (and fewer still that successfully place you into the Star Wars setting in so compelling a fashion). The ability to order one teammate to go plant an explosive charge on a nearby wall while you direct the rest to concentrate their fire on a single enemy really does add a lot to the experience. Plus, it's a relief to find that its controls and options are designed to accommodate anyone playing it on a PC (seriously, screw The Force Unleashed). It's not perfect, but it's definitely worth a buy - especially at only £2.
