Anyone else noticed this? I had no idea you could fight Dragons within cities, what with them being separate cells and all - but I just left Blue Palace in Solitude to find a Dragon swooping down to attack - after it was dead all the townsfolk crowded around commenting on it, really cool sight to see.
Yes, I've noticed this. So far, I've fought 3 dragons in Riverwood. (Yes, 3 in this small town) In Solitude, a dead dragon spawned in my face. Free soul. I was surprised though that the townspeople crowded around it and talked about it.
The most I've had is a blood dragon in Riverwood, and a regular dragon in Solitude, which randomly spawned when I walked out and took out about 5 guards, it's nice to see all the people comment on it and stand around it.
I've seen two blood dragons attack at Riverwood, and a frost dragon attack windhelm. There's been a couple of settlements / camps where I've seen a dragon or two attack before too.
