The review code installed is about 3 gigabytes, if I remember correctly. Since TTP posted his take on the game, I'll mention something too.
It's good and fun. The opening level takes away your guns and it's all about platforming, rails, traversing the enviroment. Same thing in the second world, but of course then later on it's all about shooting. You can buy a few guns from the the pirate dude, but there's no separate gun shop, instead guns are given to you. Wrench is fun, seems like a mechanic they didnt have time to implement in ToD. There's one nifty puzzle where you have to move around a few statues to generate a shadow of a skull by using the magnetic wrench to move the statues around. Quite a nice break from the usual R&C gameplay. The production values are impeccable, But the story isn't advanced seriously at all, which I was bummed about.
15$ sounds pretty good value to me, hoping that the Europrice is then 9,99 euros. Again, the game's localization is exemplary, with lots of European languages in there. Depending on what language your PS3 is set, the game'll use that if it's got it.
The game was pretty much done around the time Trophies were announced, so no wonder there's no support for it. There's none of the usual golden bolt collecting either.
