What surprised me was he was worried about some 30mb being moved on an harddisk. What is a harddisk? Is that, that clicky noisy heavy box from the past, which is used today to mostly store backups? Or the large games you don't play? Large as in, over 50gb.
He needs a modern PC and to try a modern game to have a different perspective from mid 2000's that currently seems to be engraved in his mind. Someone who can't buy a PC better than that won't be able to buy LFS either.
And you could test how optimized it is on a high end PC. You don't need to develop it on an ancient artifact to have an optimized code. Plus, HDD's are extremely slow. Add up a few seconds of waiting everytime you move something. This would add up to hours in a short time. Even SSD's feel slow nowadays when you move bigger files, compared to NVME's.
If people are surprised about the daily logs, it shows me that they don't even know how game development works. You stitch up everything knot by knot. And the knots you stitch somewhere else may mess up the previous knots you already made.
That also makes it clear why people are suggesting "improvements" that are actually their personal taste, like "My favorite app doesn't work after the update. Now I want it in the current version." The app that is probably used by less than ~10% of the players.
That will at least make people realize that it is a bit harder than they think.
