I prefer larger but not massive I have 8 now could see maybe 12 maximum.
Mine are newer so less upkeep, some games don't get played a lot but I still like having them around. PotC for example I don't play a lot but when I do it's still fun.
Great for parties if you have a nice big collection.
I know a guy with 40-50 but I think that's over the top. I think 8-12 is the sweet spot.
