This is on my list of games to purchase as soon as it drops to a respectable price...so probably this time next year when it's around £20 or so, haha. I am extremely curious as to whether it's actually a good game or just so much better than the other Star Wars games we've had in recent years. Given the awful state of the movies and the general mediocrity of the rest of the canon material, I'm dying for a piece of Star Wars media that is actually good...I'd really like this game to be it, but I'm not prepared to put forward the current asking price.
But playing as Gotham's Joker with a lightsaber does sound like a lot of fun, and the gameplay videos I've seen make it look enjoyable! I'll get it eventually.
