MMORPG

I was reading some stuff at a message board, and someone posted the acronym MMORPG. I found out that it means massive[ly] multiplayer online role playing game.

Wikipedia says it's "massively," but a popular MMORPG site and other sites say it's "massive". I don't know what was used first: "massive" or "massively", and I don't know what's "correct." But it's the closest we've come to a holodeck.
