Somewhat of a fair point. I was more so referring to back in the day where it was not a given that a game would release on steam. I clearly remember the old videos from Totalbiscuit where that was a point worth mentioning. Asset flips and the like just couldn’t be released on steam, as everything had to go through at least mid sized publishers (not an ideal solution by any means). This meant that you couldn’t get many indie titles and some bigger publishers didn’t want to use steam either, but those games that were available on the platform, while not guaranteed to be good, were at least not broken or complete trash. This changed with the introduction of steam greenlight and the later removal of almost any barrier to entry to release something on steam and that bothers me a bit.
Don’t put yourself into an even more miserable situation when it doesn’t even benefit you in a measurable way.
E.g. Lights/dark rooms: Let’s say you use a 5W LED light bulb (which should be bright enough to decently light most rooms). If you leave that running 24/7 for a whole year, that is going to cost you ~13€/$ (0,3€/$/kWh). You are not going to keep it running 24/7, you are not even going to run it half the day. It is not worth 5 bucks to spend the whole year in darkness, no matter how little money you have.
Obviously turn off the light when you’re not in the room or it’s the middle of the day in summer, but be reasonable with yourself.
The same goes for food: Sure, buying cheap staples (in bulk if possible) is a great idea, but don’t try to save 5 cents if that means skipping on the salt, herbs and tomato paste which would take your 2/10 bland bowl of carbs to at least a 7/10 and give you something to look forward to.
