Anyone know where can I download video game clips?
Youtube has tons of them if you search, other game sites like gamspy, etc, have video game clips as well. If you have a PS3, sony's online store has preview videos that are way better than any of the online sites.
There must be plenty of them on YouTube. Search for the one you need and download YouTube video with some freeware tool like http://funadvice.com/r/1580fi2qshv It's pretty easy.
