Looks like you have a golden opportunity.
You have proven your ability to a not insignificant player base, given them a great game, but tripped up a bit on aspects of the game that impacted things in 2nd, 3rd and Xth order ways that were kind of unknowable before you tried them.
You can now take that knowledge away and re-iterate, a clean slate, no band-aids or spinning plates.
I still "play" GO every day, it's part of my routine, log-in click, build up slowly.
I think you undervalue the learnings from GO. You got the hard part right, a slick, visually appealing and engaging game.
Maybe you find new pitfalls in the next game, maybe some issues can only be mitigated not fully fixed, I don't know.
I do know, I am looking forward to seeing what comes.
One comment on GO , I don't engage with the tile/golem game at all...I tried to, but I couldn't figure it out, it all seemed to whizz about in way that I couldn't fathom. Maybe some learning materials/reference material for any future version would be useful. I tried to play it, wanted to play it, but gave up and ignore it now
