I'm modding this terrible game as we speak, and it's a pain in the ass. Modding Morrowind is fun because the game is already good, and modding Skyrim (SE) is fun because the community has set up trillions of guides that more-or-less allow you to mod the game into a near-playable state with your eyes closed. It also looks
PRETTY. Oblivion is just dreadful. Any small fuck up, even while using MO2 or Wrye Bash, seems to affect the game in such a way that you need to reinstall because it stops reading the ini file or whatever. Shadow/lighting implementation on ENBs is shoddy at best and some of them have a tendency to break the most popular UI mod, and Oblivion Reloaded seems to receive periodic updates which
break everything, meaning that the problems you're encountering are not the same problems that people has six months ago. Want to quicksave or autosave in Chorrol or Bruma? Go fuck yourself, the game crashes.
Oblivion Reloaded was also updated to straight up no longer work with ENBs, so if you don't want to deal with the headache of
sort of making them work together, you get to fuck around with the ini files for OR's various shaders. This of course requires
work, which is anathema to me. Also you can't use the Enhanced Camera or Mounted Combat mods, instead having to opt for OR's own in-bilt versions. Think you can just get away with turning the features off in the config file, deleting the relevent meshes, and installing the mods anyway? Nice try, dumbshit. The game crashes. Getting Morrowind to LOOK GUD basically requires you to download MGE XE and maybe overwrite some shaders, like with that
tropical water mod, or maybe mess with the lighting coefficents when using the STEP shaders. This takes two minutes. Getting Skyrim to look nice is slightly more involved, because while the ENB binaries are more advanced, and easier to install thanks to the
ENB manager (which I tried with Oblivion, resulting in it spewing all the files back into the main folder anyway), you do need to fuck around a bit with DynDOLOD, but that's easy enough once you've watched a tutorial.
Of course, once you finally get all of this shit working, the modding scene is pretty decent. You have over a decade's worth of things to pick from, with plenty of mods that sort of fix the combat (nothing on the level of Skyrim's Ultimate Combat 3.0 mind you), mods that add plenty more quests to factions (faction mods for Skyrim are dreadful or non-existant), and a variety of total gameplay overhauls that sort of play nicely with one another. Maskar's Overhaul is really fun from the small amount of it that I have played around with while testing. Like Skyrim, it seems to be less about playing a video game, and more about LARPing, but the vanilla western fantasy aesthetic gives you oppurtunities to LARP in a different way. There's even mods to add some of the functionality back to magic, without having to use the ridiculous Midas Magic mods etc.
All I could really ask for now is some sort of functioning Damage Threshold/AR system, so that blunt weapons actually have a reason to exist (did you know all Maces do the same damage as equivalent Longswords, but
swing slower?), and maybe a climbing mod ala. Maskar's Overhaul, but that was actually tied to the Acrobatics skill.
