The original 36 items that were available in pre-alpha 1. Legends of Equestria now features around a hundred items.
In these events, development on the game would be paused, while the cloud-based development servers were repurposed to relay necessary data that allowed the game to run on temporary clients. Open Server Events were integral in helping the team stress-test their game infrastructure in a variety of real-life contexts, including a DDoS attack on February 2015
