I'm sorry but I think that sounds like way too much work and sounds like it might end up in a BFBVFS. Where did you find this Sims 3 complete thing at? Sounds fishy, just get the real individual torrents like everyone else and do it the right way, not this shit. Just my opinion.
Well obviously it's an Arr'ed compressed version. I thought I would give it a try after the 1.42 update completely fucked up my installation when it failed and I had to reinstall when I got Seasons.
It's a 3 disk installation. Download 17 torrents? I would never give this that much time especially when even stuff packs are over 1GB.
