WoW, EQ2, SWG Content Updates
Several of the larger commercial MMOGs are gearing up for updates in the next few weeks. The Everquest 2 Producer's Letter details more quests and PvP news, SWG's Patch 19 has smuggler updates and animation fixes, and World of Warcraft lead producer Shane Dabiri offers up a Battleplan for your perusal. (N3rfed has some leaked patch notes, if you're so inclined.) From the WoW Battleplan: "Some of our upcoming plans have already been mentioned on our community site. For example, in our next major update, we will be releasing Blackwing Lair, a 40-person raid dungeon, where you will be able to battle against the epic dragon Nefarian and his minions. We are also working on a 20-person dungeon called Zul'Gurub, and the mysterious lands of Ahn'Qiraj in Silithus. Outside of dungeons, we want to continue adding new world events, such as a carnival that will take place in Mulgore and Elwynn forest."
I hear Second Life is something of a better setup, but given I've only heard of it via /. I can't say it's been that successful.
Or in a less glib manner, because allowing players to create content causes three issues.
There's a limit to how many programmers you can throw at a problem and receive any benefit. If you throw the optimal(or at least near-optimal) number of programmers at the current issues, why shouldn't you have a second separate team working on new unrelated code. With a sensible design so that new development can be kept sufficiently non-intertwined with the existing code, nothing short of a full scale design change due to a fundamental architecture bug would prove problematic, and you'd get the current bugs fixed at the soonest possible point in time plus have new content delivered earlier. Seems win-win to me. Admittedly, skimping on work on the current stuff to work on the future stuff is stupid, but that's not a necessity...
