Pangaea666: Pretty easy to get frustrated when you have a problem, search for solution online and find 10 different threads with 25 different solutions, with no idea to tell what is best (and often many of them will fail, leading to lots of wasted time).
Not to mention:
* Threads where the problem isn't solved at all (and the thread may be archived at this point).
* Threads where the original poster said something like "I figured it out", but does not post the solution (and nobody else does).
It can be quite annoying to run into either of these type of threads, especially when they come before threads with actual answers.
(By the way, if you ask a question and later figure out the solution, please post the solution you found in the thread, either as a new post or an edit to the original post. This applies to all Internet forums, including (but not limited to) GOG's forums.)
Pangaea666: But the former is easier to get working without needing to fiddle about with console commands and whatnot.
I highly recommend learning your way around the console. For some tasks, it can be a lot faster and more convenient than using a GUI. For example, if you want to copy every pdf file (but not other files) from one directory to another, all you need to do is something like "cp *.pdf path/to/targetdir"; much faster than having to manually highlight every pdf file in the directory.
You aren't going to hose your entire system unless you get root access (for example, via su or sudo); you could lose your data if you make a mistake with a command like rm (so a backup might be good to have), but you will still be able to boot your computer and restore that backup (you *did* make a backup, right?).
Also, once you learn your way around the console, you can start writing shell scripts; you might even decide to learn a language like Python for those times when shell scripting gets ugly (like dealing with spaces in file names).
