I have the GOTY edition installed, no mods. I can't skip any of the intro credits (for lack of a better word) and when I try to remap keys or type in the character creator the game simply doesn't respond to the keyboard.

Please be more specific. First of all: Do you launch Oblivion directly, or via Galaxy? If it's Galaxy, I suggest to run the launcher or the oblivion.exe directly, just to find out if it makes a difference.
It looks like you get to the character editor. How do you get there? With the mouse or with the keyboard? Have you tried to get to the Options with the keyboard (direction keys)?
Regarding the intro: You can skip the Bethesda intro and the "IV" intro with ESC (at least during the first couple of seconds), but you have to endure the "Loading" screens.

Another game that requires hours of setup to even play the game on a modern system.
Foh. I have shit to do, I can't just sit here for hours doing literally nothing but set up a game with grueling annoying dated interfaces.

Sucks for multi monitor, can't alt tab for shit, mouse constantly disappearing, shocker. No one mentions this, just cream their jimmies about some old game on your pentium that you still have from 20 years ago.

Are you talking about problems you've encontered yourself, or is it all based on hear-say?

Oblivion was first released 2006 and represents the technology of 2005/6 (and quite well), What do you expect?
With that said, on my Win10 64bit PC installation is quick and painless, launches out-of-the box - no further work required. I can alt-tab and my mouse doesn't disappear. I must confess that I'm one of these dinosaurs from long forgotten times who are happy with using one monitor only.
Oblivion does have its problems, but most of them are on the software side and have nothing to do with aged vs. modern technology.

To avoid more suffering from out-of-date technology, I strongly recommend to keep away from software developed in times where this out-of-date technology was "modern". And bear in mind that whatever you consider "modern" today will be stone-age in 15 years, probably much earlier.
Leave it to other people to enjoy games for reasons which have nothing to do with "modern" or old technology.

Sorry it took so long for me to reply. I launch it via Galaxy. I'm going to try launching it directly to see if it works there. I can get to the character creator using my mouse. It's been a while but IIRC I was pressing ESC to skip the intro, but it wasn't doing anything. I thought it was just unskipable but I noticed something was wrong when I was trying to type a name into the character creator and it wasn't doing anything. It's like the game wasn't getting any input from my keyboard.

Sorry, I hope this is specific enough, thank you for replying to my post.


UPDATE: Go figure, I reinstalled it and tried again and it seemingly works fine. Thanks so much for the help, I really appreciate it!

You're welcome - have fun!
