It occurred to me the other day that maybe they are! In case you're wondering what I'm talking about, I mean games like EGA Trek and Star Fleet I, in which you command a ship on a grid-based map blasting Klingons or whatever the enemies of the week are with phasers and photon torpedoes. Sure, you don't move the ship with the numpad or anything, but the map is grid-based and procedural, and there's definitely permadeath! (Well, except in Star Fleet I, where you have some persistent scoring mechanisms between games.)
