My Reaction to Completing Final Doom

I just finished TNT Evilution on the "I'm too young to die" difficulty. I enjoyed this perhaps more than "The Plutonia Experiment", which starts with some dull maps and the secret maps were ridiculously difficult even on the easy difficulty. My stress levels playing those maps were at an extreme unhealthy level.

I asked ChatGPT what it thought of this, and it came up with...

'That’s a pretty reasonable take—and honestly, you’re not alone.

TNT: Evilution vs. The Plutonia Experiment comes down to very different design philosophies:

  • TNT: Evilution leans more toward atmosphere, exploration, and gradual escalation. Even when it’s challenging, it usually gives you space to breathe.
  • Plutonia is basically a gauntlet. It was designed by the Casali brothers to punish mistakes—tight encounters, lots of traps, and enemies like Arch-Viles and Chaingunners placed to maximize frustration.

What you felt with Plutonia—high stress even on easy—is kind of the point of that megawad. But that doesn’t automatically make it more fun. There’s a difference between:

  • engaging challenge (TNT often hits this), and
  • constant pressure with little recovery time (Plutonia at its worst)

Your comment about the secret maps is especially telling. Plutonia’s MAP31 and MAP32 are infamous for being brutal regardless of difficulty. On “I’m Too Young to Die,” you get more ammo and take less damage, but the encounter design itself doesn’t fundamentally change—so the stress is still there.

Also worth noting: early Plutonia maps do feel oddly flat compared to what comes later. It ramps up hard, but not always smoothly.

If your stress was at “unhealthy levels,” that’s a good signal—not a weakness. Doom is at its best when you’re in that flow state: alert, but not overwhelmed. Once it tips into constant tension, it stops being fun and starts feeling like work.

If you’re continuing with classic Doom content, you might enjoy:

  • Final Doom TNT on higher difficulties (it scales more gently)
  • Community WADs that emphasize exploration over ambush spam
  • Or even revisiting Plutonia later with foreknowledge—it becomes more of a puzzle than a panic simulator.

Terminator: The Story of the 6502 Code You See Onscreen


@john2001plus
The 6502 was a very simple chip, but it was cheaper and faster than other 8-bit chips.

I loved programming the 65816 on the SNES.    I wonder how the world would be today if we got 32 and 64-bit versions of the 6502?

BATTLEZONE on Atari 2600 | Tank Combat in the FAR Future of 1999!

Battlezone is one of my favorite Atari 2600 games.

However, it is hard to get a good score.

My other favorite Atari 2600 games include Boing!, Pac-Man Jr., and Pole Position.

Bomb Man (Tomy Tutor)


4:24 These simple 3D mazes are easy to write; they can even be done in BASIC. I experimented with this kind of maze, but never turned it into a full game. I wrote more complex 3D effects on both the TS1000 and TS2068, but since they were in BASIC, they took forever to render. On the TS1000, I created a rotating oscilloscope with a 3D projection. I did this on the TS2068 as well. On the TS1000, I was able to animate it by storing 16 screenshots in memory and switching the screen pointer. It looked incredible. On the TS2068, I implemented a kind of ray casting that created a 3D chessboard with an infinite number of squares projected out to the horizon. I also created a 3D pyramid projected in a 2.5D isometric view. Unfortunately, I sold all of these effects—along with some simple BASIC games—as a product called The Great Game and Graphics Show. It sold well, but in hindsight, it was closer to a demo than a fully realized product. It was 1984, and I was just getting my feet wet writing software for personal computers.

68000 - The CPU ahead of its time


I found the 68000 easy to program.  The instructions are very straightforward.  i.e. move 8, 16, or 32 bits to a register.  Add two registers.  Move 8, 16, or 32 bits to memory.  It is almost as easy to follow as C code.

Likewise, I found the Z80 easy with its many 16-bit registers.  The 6502 has few registers, which is more difficult to program.  However, the 6502 has a trick, which is zero page instructions that use fewer clock cycles to access the first 256 bytes in memory.  Programmers can use the zero page like registers.

The Plutonia Experiment (100%) Walkthrough (Map30: The Gateway of Hell)

I finally finished The Plutonia Experiment on "I'm too young to die."   The game is no cakewalk on the easy level of difficulty.  The secret map 32 and the final map 30 are highly stressful.

This is a very imaginative and enjoyable set of maps.  I like them better than the more mundane Doom II maps.  This is what Doom II should have been.

The Plutonia Experiment (100%) Walkthrough (Map32: Go 2 It)

WTF. I played Plutonia Map 32 on "I'm Too Young to Die," and it was a nightmare. The arch-viles kept resurrecting enemies, and I had to kill multiple cyberdemons. I left maybe five of them alive when I hit the exit and still got 98% kills.

I had to keep saving my progress incrementally just to get through it. The map left me with a stress level that honestly feels detrimental to my health. I can't imagine playing it on a tougher difficulty.
