There's a good point in the argument about taking things for granted. Yes, as a kid we could only play what we owned, unless we somehow managed to obtain new games all the time, but even still, in 1994, what other games were around like Doom? Like Doom. Besides Wolf 3D, options were pretty limited. Maybe "take for granted" is bad wording but with more choices now it's easy to find something you like and don't like but back then it's not like we had thousands of FPS games. Whether you like Doom or not, it and even it's successors like Quake, did things that were just revolutionary or that nobody had seen before. And until more games like that came around, it's what we had.
