They disappeared for a couple of weeks and the URL that was around had to be changed, could've been around then. Nintendo has always had a... complicated relationship with fan works, and I'm firmly of the belief that I want things to actually be released and playable on the hardware itself. I fully expected Square Enix to come at me, but it never happened and so much of Don't Nod now being aware and following... well, when the co-creator of the entire franchise approves of how it went, what more can someone ask? ;)
Definitely easy to get burned out. Or be tempted toward other things (Lost Records: Bloom & Rage...), or wishing a newer version of GB Studio with all the fancy new things since 1.21 would work for branching conversations without requiring hundreds/thousands more things added...
All for the love of the game, I guess! :)
