I came across a website today that has some free training videos for Unity and Source. I'm sure some of you will be interested since there's already so much info out there on UnrealEd. I haven't had a chance to check these out, so I can't comment on the quality or content, but feel free to comment if you do watch them.

Nice find! I personally learnt the source engine from 3kliksphillip on youtube back in the days when I played Counter-Strike: Source, and I have to say he's great for teaching the fundamentals of level design, especially because he has such a solid knowledge of the engine and a great workflow.

I find it pretty hard to find good tutorials on unity, but this may be it!

Also, here's 3klikphillip's youtube channel: http://www.youtube.com/user/3kliksphilip
