I counted (haha bet you thought I couldn't) and I have 93 factions available, but as stated above, I am just a rookie, so you can assume I am not really trying.
Click, click, run. A mod is something you have to download from Nexus, activate, run LOOT, pray it works....oh sorry I only have to do that for Skyrim, don't have all that whatever with GC3, but what the heck a mod is supposed to be real work right?! Can you really blame me for not getting that?!
And I have run insane with 60 or 70 (I can't count everything! Sheesh) factions and I found that the game does run smoothly on my crummy four year old computer.
Except Seilore is right (don't you get tired of that, huh? I mean what the heck) the ship movements are a bit jerky. That's the only thing I noticed though. As a rookie though I probably missed all the important stuff. I really have to get back to playing this horrible broken messed up piece of garbage, I mean if it really was decent and worked right I would have my 1000 hours in by now and I wouldn't have people calling me rookie...OUCH I think my feelings are hurt*.
As far as the UP, well, it's way too many peeps to count, now that I am tired of the brain exercise. They don't vote my way anyway how broken is that?!
*jk, about most everything actually, sorry, just can't be serious when I read some forum posts, I am a horrible person too, and dang old to boot.
