I first played SNES Doom during my childhood. I remember that at the time I didn't know we could choose the episode and difficulty so I always played from the start in HMP, so it took me some time to reach the end of the game but I was pretty proud of me when I finaly defeated the Spiderdemon.
Then I played PSX Doom and Final Doom a lot, loved the new sounds, musics and the dark mood.
At some point I figured out that all of the original maps weren't included in the console versions (especially in Final Doom), so when I got a computer I installed Doom to play the remaining levels, and then I discovered there was quantity of fan made new levels.
I'm really impressed by all the good stuffs we can find around here, I think I'll never get tired playing this game
