Doom, Grand Theft Auto 3, Final Fantasy 7, Wolfenstein 3D, Resident Evil and Metal Gear Solid there are my favotite games of all time. Doom is definately a classic, the first time I played it on the computer, I was hooked. There's no telling how many hours I spent on this. As of many, I bought Doom the first day it came out on Playstation years ago. So too all you Halo players that have no clue what Doom is about, everytime you play Halo keep in mind that if Doom never existed most likely Halo wouldn't exist. The whole Doom series is definately worth owning. The Graphics and sounds are now way out of date but at the time they were amazing. This has some of the most complex levels imaginable, it'll keep you entertained for hours. So many games today are like so many other games. The ones that are special are the ones that stand out. This game took a risk to be different, and now it stands as being one of the best games ever created.
