StingingVelvet: PC gaming will always require a lot of tweaking and issues to solve, it's just the nature of the beast. Though I will say I haven't had a GOG release cause me problems in a loooooong time. I remember Zork Grand Inquisitor being the last one, and that was many years ago.
This is very true. Many people who use GOG-steam-epic-what have you and get games that more or less run after installing with a few clicks don't know how good they have it now. This is not to rag on them, but years and years back one had to edit their boot files to find ways to make games run by freeing base memory(most games needed a good chunk of the first 640k free to run), adding or removing third party drivers, make boot discs, and more intensive things like hex editing files to make them work.
Now all one has to do for many games that are system/OS compatible is just install and play, which has led to many becoming too reliant on things working out of the box(same with google and the net making people reliant on knowledge being quickly available to the point where some need to re search the same info every other day).
To keep myself sharp mentally and skill wise, I often keep track of old and new sites with tech help for games/etc & also edit config files for various games to learn new ways to do so for new config types and schemes to keep the knowledge fresh in my mind in case I need it again and cannot access the net easily.
