Did you play Rise of the Triad as well? Similar play style to Doom and Wolfenstein. I've been gaming since Snipes (1982) so those games were state of the art back then. I get a kick out of the old Doom chambers hidden in the modern Doom games. I still had my floppy disks for some of those games until a couple of years ago but no more drives to support them. I have a 3 1/2" in storage but I don't think I have any more 5 1/4" drives kicking around.
