There is nothing interesting on my YT account, but here are some users you might like to check:
http://uk.youtube.com/user/Retroplay - great gameplay, mostly amiga and other retro versions of games (including DOS if I remember correctly). Only person I know who finishes most of the games without loosing a single life without any cheats. (some of those games are quite hard for mortal such as myself)
http://uk.youtube.com/user/cubex55 - Amiga long plays. All of those videos are available at their web site.
Recorded Amiga Games. Nice thing is that their account is not limited to 10 minutes. (imagine watching gameplay of Cannon Fodder, which is still made into 4 50+ minutes movies
)
http://uk.youtube.com/user/DerSchmu - C64 longplays. (Perfect for Sebatianos, isn't it??)
http://uk.youtube.com/user/laffer35 - When you tired, you can watch one of laffer35's 100 games in 10 minutes for different platforms.
