I think something was discussed back in Dom2 about it. The conversation went something along the line of....
1) how can I record a combat?
2) fraps
3) upload to youtube
4) edit it to add funny comments or add dance music?
5) Mac(imovie) Windows(windows movie maker)
6) real movie, me and my buddies, I want to play Lord of the Wild who draws droves of wild party girls out of the woods.
Well from there it went off track
But it does sound like it could at least be your 15 minutes of fame on YouTube (plus abit of advertising for Dominions) if someone wanted to do it. Better than the backyard wrestling or just-another-starwars that I keep seeing there.
