Does anyone still play Id Software's well known software titles "Doom" and "Doom II" ? I sure do, because I love the huge community, the source code for the engine is out thus one can add their own stuff to their own source port for people to enjoy, the tens of thousands of addon maps available to play due to the availability of numerous map editors and others.
Being involved in the community since 1996, I have made a number of maps (at least 30 or so, found on /idgames/) and contribute to an open source random map generator called Oblige (Under credits as Mr. Chris).
I also have a bunch of Doom videos on my Youtube page, so please check them out if you still like the game.
On top of all of this, Doom and Doom II can still be purchased on Steam for a low $10, not to mention Doom turns 18 this December!
