I've only played one other late alpha and beta. LoTRO. Granted, much larger team. There was a point in early Beta that it was called "Lord Of The Quests". Mainly you couldnt walk 10 game world feet without tripping into a NPC nagging you about 10 wolves eating their sheep or some such. Then they dialed it back to almost no quests. Same thing with Agro NPCs, etc, etc. They would go to extremes and watch the reaction, and then find peace some where in the middle. However, these cycles were about 2 to 4 weeks, depending on the complexity of what was being tested.
Silverback or itty bitty fella?
