I have a pretty big collection of SW commercials of varying quality - I'll upload it later for whoever wants it, just in case it could be useful.

Some of the SW commercials can be found at the sites above - again, the quality is kind of low, but I don't know if anything better is out there.

I am trying to track down any SW video game commercials or advertisements for a project I am working on. If anyone could help me with that, I'd appreciate it. Some of our two projects will be overlapping.
