There were a few awesome voice mods for Oblivion. I often found myself using the Garret voiceset (from the Thief games). What amazed me was how spooky accurate some of the voices' comments were.
Like, I was using the Thieves Arsenal mod, first time on that particular playthrough. I go to leave with my new tools, and Basso calls me Taffer as usual. I get out the grate, and then Garrett pipes up "What the
hell is a Taffer, anyways?" My character stood there for five minutes as I proceeded to roll around on the floor laughing like hell. Spooky accurate. Other things that come to mind are the allusions to enemies I'm fighting. I'd have an arrow beaded on somebody, and just as I'd go to fire someone else would walk into my LOS and Garrett'd say "I could pick that guy off with an arrow, but if I miss I'll alert them all" or something to that effect. Brilliant mod. I wish
that aspect was in game. The whole mod was maybe 7 megabytes, and that series of mod had so many voices it was amazing.
I liked feeling that my character had his input on a situation, as well as my own opinions. I'd find myself taking what the mod was saying as actual input, as well. I usually play "myself" (Not that I imagined I was actually there, but I when I did my "roleplay" I used my own logic and opinions, not a characters) but having that extra bit of character in my character was epic. Garrett'd (I started naming my character Garrett, after I took that mod) often point out things that always seemed relevant. I dissected that mod and couldn't find out how it was doing it. It was kind of neat that I'd be "telepathically" working with my character, kind of like I'm sitting here on a voice mic while he's doing his work.
If I could have that with my Skyrim, I think I'd do strange rituals outside gamesas HQ.
