No, I buy my games to play them.

I agree with viperfdl, above. Actually, what kind of question is this? Why would anyone amass things to not use them?!! Or to not try to use them, at least. I understand there's little available time nowadays (and some games take a lot of time to be completed), but at least one should try playing all his games, even for a little time on each game, to witness just what he's bought!

Read the first posting of this thread, it is clearly explained there why this question was asked.

I might have missed an expansion the first time, the total right now is actually 102,89 €. See the attached picture.

EDIT: Even worse, 112,88 €. I missed the Apocalypse expansion.

Not anymore because after i stopped buying Steam games i realized how much time it would take to complete all the games i haven't finished yet...

I currently have 388 hours left to complete all the games i haven't finished in my Steam library, and i have 64 games i haven't finished yet in my GOG library... Most of the games i have not completed yet i got for free.

Yes? Why not? At the asking price I don't mind owning a piece of history. Down the line they might not be available, but that's not entirely the reason I'd collect. It's not a very serious hobby, but I prefer replaying games more than I do completing them.
