Since discovering MUD in the mid-1980s Daniel has single-mindedly pursued the creation of social spaces for collaboration and creative play. He pioneered free to play, non-hack-n-slash MMOs, complex player economies and the puzzle + world + RPG genre that would grow to generate billions in annual revenue.Daniel's commercial experience building and operating profitable games with long-term player communities dates from the early 1990s co-founding Avalon, a multi-player roleplaying world. In the late 1990s his quest was to build an MMO based on the Lord of the Rings, first as a startup then with Sierra On-line. In 2001 he co-founded Three Rings in San Francisco to create Puzzle Pirates which grew to build and operate a fleet of online games. Three Rings was acquired by SEGA in 2011, going on ship to a number of mobile and online titles. Daniel stepped down from the studio in 2014.In 2015 Daniel was recruited as Head of Social VR during Facebook's early forays into social virtual worlds. In 2019 he co-founded GGFolks with former colleagues to develop Puzzle Wizards, a mobile and PC cross-platform community oriented game world, currently in early-access.Daniel lives in San Francisco with his wife, who is a childrens book illustrator, their two children, a large dog and a spooky French black cat.
