Th thing about youtube is that it's a good place for posting videos to lull people in with weird and wacky claims. Fake trailers for example (Trailers for the Oblivion mod Nehrim have been posted numerous times as Elder Scrolls V Trailers) Another fake claim is one thats popped up once or twice in the New Vegas support forums. (Download a suspicious file from a suspicious link, install it too your PS3 or Xboxes hard drive and it will magicall fix all the games problems on both consoles)
In other words don't take things at face value.
VERY true. There are some weird people who WILL go to a lot of lengths to put false clamis of things they`ve done that can`t actually be done and has been faked one way or another or is not what it looks like. I`ve seen several, including Battlefield Bad company fakes.
Do`nt believe everything you see on utube just cos it moves. Some people like to make fantastical claims just for attention. Wait for proof, like you can actually download and play it. If they`re iffy about that, then be wary.
By the way, saw something like this for Oblivion years ago, that turned out to be fake- never heard of again.
