FO1 + 2 Own FO3 in my opinion.
Its just to repetitve on FO3, The graphics filled to much of the space for gameplay and which ended More features ect, But on FO1/FO2 The graphics were bad but the gameplay OWNED
Yea, I remember firing up the demo of Fallout 1 on my PC waaaaaaay back in 1996 or 1997. And it was probably the first real PC game I played that suddenly opened my eyes to PC gaming. I remember flaming my first raider and fighting Rad scorpions.
The fallout trilogy really does deserve a play through. And I know games have changed along with the technology driving them... but fallout is something S.P.E.C.I.A.L. =]
I own multiple copies of the orginal games (along with some other golden classics like baldur's gate and planescape). They have their own special shelf in my collection.
