Any comments on the infrastructure for capturing the replays? Did everything get recorded? I'm used to recording all actions, ability uses, etc. but recording movement isn't something I've seen done all that often and it seems like it'd be another order of magnitude of data.

Think of a web server with a fresh SQL database with no data (other than whatever is pre-populated there by the installation.) Simply record all incoming messages to the server over a period of time and save it to disk. Then, when you want to replay that recording, start with a fresh database again and replay all the messages. Assuming your system is deterministic (no race conditions, generally not relying on a wall clock [there are tricks for this, since it's a harder problem[1]]) and you're good to go. The key is designing everything to support this from the beginning. [1] Done right, you can play a minutes long recording back in seconds, which is very useful for trying to fix a bug and verifying it against a known-bad replay.
