I don't think graphics will be an issue if you just use the max settings. You wont have to use vanilla graphics unless you are a masochist of cause. This particular style of graphics could never be amazingly beautiful. The gameplay and the people you play with on the other hand... well the gameplay anyway.
Is that a thing? I see several people using this argument, but have never experienced it myself when i go back to play a game i enjoyed before.
You also have the option to choose if you want graphics like they were in vanilla, or have a update with some chaged to texture and lighting i believe.
