This is all from Fletcher Dunn on the HLDS mailing list, because I know not everyone is subscribed. TLDR: MVM is mission based, not map based, and players can "create their own" and "it's easier than making a new map". Servers use more CPU than a 24 man game and need to be launched with a separate command and with 32 maxplayers. Putting MVM maps into a PVP mapcycle will totally mess your server up, don't do it. Emphasis mine. How we gonna test this shit? Dag, yo.
