Game in which you build your own CPU

I love MHRD, as well as TIS-100 (write assembly to solve puzzles) and my absolute favorite Zachtronics game, EXAPUNKS. They're all great examples of gaming, besides also being incredibly educational. Somehow they are actively fun, unlike a lot of other "learn to code" games that are paced wrong and are actually just tutorials. Plus what other game makes you print out a PDF of instructions before you play :)

I recommend these games to all my programmer friends. I'm definitely a better programmer for having played them.

Also, if you're not already a programmer and want to learn, I really enjoyed Human Resource Machine. It's also an assembly game but it's much more appropriately paced for new programmers and doesn't require knowledge of things like recursion.

If you're interested in hardware programming also check out Shenzhen I/O. I haven't played it yet but I printed out the manual last night. Gotta beat EXAPUNKS first :)

Interesting. It looks like basically the nand2tetris course done as a game.

I did enough hardware simulation through VHDL back in the University.

Interesting. Is it actually educational or merely entertaining?
