I'd never played Doom 3 before but my wife used to love it (I know!!!). When I saw it coming out for PS3 I thought I'd give it a look in. All looked good, but as soon as I saw that Doom and Doom 2 were included, I was in. So, what do I think? I think is one HELL of a collection! Doom 3 is cool. A very different experience to the originals. It's a lot more closed in so you dont have a lot of time to think about your attacks. The graphics are nice and the all new 3D option really adds something nice to it all. But, as good as Doom 3 is, I've found myself playing the original Dooms more so far. They look lovely and have all the episodes available. The controls map very well to the PS3 pad and it feels great to play. The only thing I didnt like when I first loaded it is that it's not in widescreen. There are black bars down the left and right sides, but to be honest, it didnt bother me for long and now I dont even notice it. I thought it was great that they even have their own trophies for them too.
I've given it 5 stars because this collection is just fantastic. It's presented so nicely and despite the originals not being widescreen it all looks as I'd have expected. Plus...IT'S FRIGGING DOOM!!!
Buy it and be happy!
