After all this time I’m still slack-jawed at how much content they crammed into those old DOS games. Months ago I fired up Blood to see what all the hype was about and oh my god, that thing is a monster. I tapped out somewhere after the carnival level. I don’t even want to imagine how long it takes on Extra Crispy (more enemies, makes them all twice as hard to kill).
Extra Crispy is explicitly said in the Readme file (god remember when games
had readme files?) to be meant for co-op play, so that should tell you something.
I was having a chat with a friend last night. One thing that's funny about a lot of these retro FPSes is a lot of them fall into a zone I call "you had to have played it as a kid."
Blood came up as a notable exception. I, in fact, did
not play it until just a few years ago, and yet it quickly became my favorite of the Build Engine FPSes--even beating out Duke Nukem 3D, which I
did play as a kid.
Shadow Warrior... is probably in the "you need to have played it as a kid" zone. That one, when I finally played it, I just could not get into it. I liked it enough to get through the five episode demo campaign but not the main bulk of the game.
Also I've always wondered how 3D Realms got away with literal child nudity in 1997. She appears
eight seconds into this old Gmanlives video if you don't know what I'm talking about. I would be very shocked if not-Sasami is still there in the modern ports/remasters.
.... I always liked both Heretic and Hexen, though yeah, Hexen can be a bit of, shall we say, an "acquired taste" in some respects. One of these days I need to finish Hexen 2 and Heretic 2.
