As we have mentioned several times across a variety of media, our goal is to focus on permanent content additions that foster continual play rather than one-off events that are limited in time. In holiday specific situations, like Halloween for example, our goal is to jump off previous year's content and create scenarios that can be built upon in successive years. With the release of Time of Legends and the Valley of Eodon we did not want to simply abandon that content in lieu of something new, leaving it unfinished, as has happened in the past. From a design perspective, I am committed to fleshing out the remainder of the Valley of Eodon as well as bringing players on the journey through the history of its native peoples and creatures using The Savage Empire as inspiration.
When it makes sense, we can pull in elements of RL holidays - the underlying theme of "Love" in the Valley of One quest, for example. As far as what happens between UO & DAoC, one cannot simply hop on the UO Team and start implementing content. The development process between DAoC and UO is like comparing apples to oranges, and while we do share resources between all our products these resources are exclusively on the backend, the content creators are individual to each game. The idea that somehow we were unable to "scrape up enough resources" to put together some kind of global event for Valentine's Day & St. Patrick's Day makes it sound like accomplishing that task is simple and unimaginative - I can assure you it is neither.
