There are. These days there are OpenMW-specific mod packs. You run one command to download everything, another command to install and configure it. The instructions are really good, it's hard to mess up.
Thanks again. That is much easier than in the past. Fired it up yesterday, tried downloading 30+ mods manually, got a premium nexusmods account to automate and speed up the downloads and it just works. Damn, there is a lot of content and upgrades from a few hours in it. Wish I could be a teenager spending many hours a week on it again!
Yeah. Especially Tamriel Rebuilt adds a boatload of content. They're still working on it, but a good chunk of the mainland is explorable and full of quests. :)
