Finally got the Wingspan Nesting Box. It fits all the current expansions and has room for the future. I swear it must clock in at like 20lbs.
Still a little annoyed that all the Wingspan stuff that holds sleeved cards won’t fit the mote or less widely available and “standard” sleeves (Wingspan cards are not the same size as many other games) but thats not really anything a little 3D printing can’t fix.
If it makes you feel any better, I actually haven't played Oceania, even though I have it....
