I used to love Doom Legacy. IMHO, it was one of the best source ports, and one of the few available for GNU/Linux (and FreeBSD). So, I had a small section dedicated to it. Here you have some screenshots of my playing doom, and unnoficial CVS snapshots of doom legacy for GNU/Linux (binaries with a nice installer even). However, I haven't played Doom in a long while (over a year in June, 2003) and haven't updated this section in longer than that (the last snapshots are from the beggining of 2002). This is a dead page now.
