  By making the roads single-direction and roads owning the movement, I think it’s been made equivalent to a conveyer belt… which means factorio’s conveyor belt optimizations might be relevant.Eg storing the delta between items rather than tracking position directly, because the distance between cars is static for the length of the road, except during compression, insertion or removal of a carhttps://www.factorio.com/blog/post/fff-176

  I love these posts, because I always wanted to get into game development and never found spare time. Thank you so much!

  Great! I'll finally be able to buy all commerce spots in Berlin (cheapest city) to avoid any competition, and _then_ open a restaurant.I used to deal only with "ice cream" (illegal weapons) trading, buying in one city and selling them on another, to quickly earn lots of money, and then buying commercial spots but never opening them (too much hassle, having to micro-manage shops).But after having bought about 200 or so, the game would inevitably crash a few weeks after my save file, so in the end I stopped playing it. I never got the exact details about the bug, but I hope this remake won't have it!Besides that, the most fun thing was trying weird pizza recipes and seeing that the taste algorithm was a bit weird. I could put lots of chicken, or pineapple, and mix a few ingredients, and have some age groups rate them very highly.But sabotaging the competition was still funnier than handling a normal business.

  The third image showing the arrows for traffic direction gave me a tiny eureka moment. You don't need complex rules for what cars can do at an intersection. You don't reason about the intersection at all. You reason about the lanes!At each choice cell, you just weigh the turn lower than going straight when randomly deciding. And if you don't want U-turns, you set a rule like it describes, or any sort of "cooldown" on turning.

  > cars don't need to know where they're going. Each road tile type carries its own direction. Road tile 0x16 is the bottom part of a horizontal road, meaning that cars can only drive from left to right on these roads.There's always a simple explanation for anything that looks too complicated for an old game to do.

  My high school girlfriend and I played this game all the time; trying to build the pizzas to get the best score was always super frustrating. It always felt like I could be a single pixel off and get a really low score, but I loved building my "empire"

  Anyone know of any communities/game jams with the theme of "has no business running on such low hardware requirements"? Kind of like the demoscene but for games.There were many games growing up that gave me such a warped view of what was to be expected from the hardware. Battletoads, Crash Bandicoot, Marathon Trilogy (Macintosh), Age of Empires (Multiplayer), Roller Coaster Tycoon (of course).

  I don't have much to add except to say, I love this trend of people rebuilding old games like this. I hope to see a lot more of this.

  I was looking for this game on GOG only an hour ago having regaled a teenager with how great it was! It’s not on GOG unfortunately.

  I see some cars disappearingedit: actually if it hits an end of a road, it spawns to a lane next to it either goes opposite direction or turns (referencing first gif)Wonder if they could have considered ensuring no cars stack on top of each other

  I couldn't understand why someone would want to reimplement Pizza Tycoon, until I realized I played it's sequel as a child, which is much maligned compared to the original.

  Fascinating how constraint breeds elegance. 25 MHz forces you to find O(1) or O(log n) solutions where modern devs would reach for O(n²) and more hardware.Same principle applies to on-chain computation: gas costs force you to find closed-form solutions. For example, computing φⁿ (golden ratio to the power n) naively requires n multiplications. Using the matrix identity [[1,1],[1,0]]^n via repeated squaring gives you O(log n) — and the Fibonacci numbers fall out for free. The old game devs would have appreciated EVM constraints.
