I was having a discussion on Ventrilo the other day with some folks in my LotRO kinship. We were lamenting the roughness of the LotRO end-game and were talking about some of the hurdles different IP-based games are having. (That is to say, games based on a third-party IP – technically, all games are based on someone’s IP.
Blizzard owns the IP related to WoW. So if they want to add space-ships or player-controlled flying mounts, the lore folks just say it’s possible and then it’s up to the software folks to make it happen. There’s almost nothing standing in the way of a gaming possibility, the lore creators just have to figure out the story behind it and then it’s ready to be built into the game.
Turbine does not own the IP behind its LotRO game, Tolkien Estates does. Everything in the game Turbine build has to conform to the lore as Tolkien imagined it. There are exceptions (like the number of adventuring hobbits running around) but the places, the overall feel of the game and many of the character names and abilities are limited by the IP. As such, players cannot be wizards (there are only a handful in Tolkien’s world), players cannot ride eagles (riding eagles is a rare privilege); the lore curtails many of the possibilities in an online world in favor of sticking with a set, third-party IP.
