I was going to wait until I had more time for a nice long post...but I didn't find any in my couch cushions so here's my inking of an idea and some tiny discussion starters...
What if there were a "perfect" game...what would that look like?
1. With subjectivity being what it is I am approaching this more from a philosophical side and not a "can you design the perfect game" side. I realize the arguments are sort of "splitting hairs" but, I was still intrigued by the thought.
Gloomhaven...I think the two-card mechanic might be a chunk of what makes it special? Also, the ability for the game to be constantly dynamic and not get old. Having no two games fee alike is a nice feature I think.
#Brass: Birmingham - I am not sure yet what the most satisfying feature of this game is?
#Scythe - Well balanced 4x game? Again, hard to say?
Hopefully you see where I going, trying to take top-rated games and narrow down a feature that makes them great. The "perfect" game would have all these features.
