While the MIPS implementation in Stationeers has some limitations (128 lines, with a maximum of 52 characters per line), I've rarely run into problems like running out of room. This is mostly because I try not to write "multi-mega-scripts" that do a ton of things. I'm a fan of the UNIX mantra of "do one thing, and do it well". This also means that I use ***aliases*** and ***defines*** a lot. They take more space than just writing things straight up, but they also make the code much easier to read!

They could do the exact same thing, but the bottom one actually explains what's going on. And it's still shorter than 52 characters. They could do the exact same thing, but the bottom one actually explains what's going on. And it's still shorter than 90 characters.
If you're juggling 10+ registers in your code without naming them, the chances of getting them mixed up increases greatly. And if you do make a mistake somewhere, trying to follow the code can be more complicated than if you used named variables.
