Hmm, there is another person on here, Kiri-ryona. We did some ryona videos of Age of Conan together and I was able to upload them to this thing called Skydrive. I am not sure if you are familiar with it. Basically, if you give me your email (send it to me via private message on ryonani) I can give you permission to access any videos on my Skydrive account. I can then upload some of my AC3 vids.
Just a warning. I am really only into Female vs Female type ryona. In particular for AC3, I focused on the Independent ruthlessly slaughtering the other three women, lol. Mostly the axe kills: high profile (running) kill from the back, and the low profile axe kills from both the back and front.
I have videos of me playing as the red coat, lady maverick and pioneer and playing stupidly to get killed, lol. To be honest, it is kind of tough for me to do that because I am pretty competitive so I need to somehow balance my desire for ryona and winning. It sucks, lol.
I also have vids of me playing as The Independent in training mode and killing the other three female characters. Oh, I also lowered the music to 0 and the sound effects to 1, which might sound strange, but it is a lot better for me since it lets you hear the death sounds better.
I even had the sound effects on 0 for a while because I really wanted to hear which languages had the best death sounds. Now that I figured out how to swap sounds, it's not as bad. Still, the swap method has some limitations, so it's not perfect.
Anyway, let me know if you are interested in any of that. Like I said, I have very particular interests, so a majority of the deaths are the Independent killing the other three.
Take care.
PS - The Last of Us multiplayer also has amazing execution animations (with the best ragdoll I have ever seen) and some great voice acting from the females. That also gets no ryona vids made for it. Can't help there, though. Don't currently have a capture device that I can use for my PS3. Oh well.
