It seems that *Hytale* as a specific game appeared in 2015, but the decision of making an Hypixel game was from way earlier than that. I'll probably only find first-party sources, but that clearly means that it was a project before 2015. In early 2014, Hypixel's MVP+ rank included "early access to our upcoming standalone game"
The wikipedia article states "and decided to make their own game in 2015" Anomalocaris ( talk) 21:24, 13 December 2019 (UTC) The interpretation of sources about Hypixel's timeline is incorrect.
