There is somewhat a pattern that members that are not very vocal (except spurgeonryan) have more games than those that like to discuss a lot.
I am more like spurgeonryan - I buy most games and enjoy them, though I am by no means a completionist.
I have bought (and given away almost half) probably 40 retail games.
Lately though I have started to download most games (that I do not plan to share/give away). Maybe 20 AAA downloaded games and at least 30 eShop games.
Not a big fan of VC though (less than five).

27 retail, plus one digital (fast racing neo).
