The topic of purposeful obtuseness in game design is tricky. Limitations can actually spark creativity, whereas definitive answers typically cannot. But sometimes I think game designers try to be more “clever” than they should.
The most recent example I have experienced is in playing Factorio. There are Conveyor Belts, which move items along them. Each Conveyor Belt tile actually has two tracks: Left and Right. There are robotic arms which can transfer items from wherever and place them on the Conveyor Belt. These same robotic arms can pull items off the Conveyor Belt from either track. However, the robotic arm will only set items onto the Conveyor Belt on the far side.
My question: why? No, seriously, why the fuck can’t we choose which side to set things on?
There are convoluted “solutions” out there for methods on how to move all items from, say, the Left track to the Right track. There are also solutions on how to construct paths such that a multi-track line is then later split off. None of these solutions involve, you know, telling robotic arms to place items on specific tracks. Maybe there is some huge programming reason why each robotic arm cannot be told to place on one track versus another. But you could certainly add a “near-side robotic arm” machine to the game and call it a day.
Or perhaps the devs are being obtuse on purpose.
Oxygen Not Included is not immune to shenanigans. There is a Tepidizer in the game that you can use to heat up water. There is an limit to how hot it can get the water though, presumably because it would be too easy to create Steam systems otherwise. So the solution is to create an Aquatuner – a machine that cools down liquid and heats up itself – and then have the extremely hot Aquatuner boil water into Steam, which then will cool down the Aquatuner in the process. It’s “clever” and involves more steps/physics than simply heating up water via Tepidizer but it’s arbitrary as hell.
Drawing that line would be difficult indeed. But I do think there is a noticeable line somewhere. People have done some ludicrous, literal programming in Minecraft using the Redstone switches and such. That programming would be a lot easier with blocks that automatically did X or whatever. The difference, I think, is that the Redstone system is “simple.” It has the basest of building blocks. In Oxygen Not Included you already have the Tepidizer. In Factorio you already have robotic arms that place items on the far side of Conveyor Belts but are capable of grabbing items from both sides. No one can say Notch or whomever didn’t add something to the Redstone system to limit it on purpose.
Incidentally, other examples of purposeful obtuseness is when a game will feature crosshairs for everything other than weapons in which it would be OP. For example, the bow in Kingdom Come: Deliverance. An arrow to the face pretty much kills anyone but the balancing mechanism is apparently taking away the crosshair so you have to learn the trajectory by muscle memory. Or download a mod. Or dangle a piece of string down your computer monitor. Balanced!
So maybe the line is artificial limitations. I’m willing to accept no bow crosshairs if there were no crosshairs for anything else in the game. Similarly, I’d accept no easy Steam generators if the Tepidizer (or Aquatuner) didn’t exist. And finally, I’d accept lack of granularity with robotic arms and Conveyor Belts in Factorio if robotic arms could only retrieve items from the far side of the belt.
But they don’t, so I don’t.
