Best Mods?
 

I like major expansion mods which enhance detail, realistic-difficulty, immersion and realism. Big fan of Ralles mod soup for SH4, Oscuro's Oblivion Overhaul for Oblivion . . . reckon I'd get into FOTRSU if I hadn't got into RAL first . . . that sort of thing . . .

So what are my best options and where would I find them?
