Do you keep games in a collection ie. A LOT OF THEM, or trade/aquire/trade

[Zlejedi]

I keep good games in collection. If I sold something on which i spent a month of my live for a few bucks it would be like selling good friend.

But for average games which i played and I know i won't ever want to play them again I'm selling them.

Now I have a huge dillema on what to do with PSP games - on one hand I don't want to sell stuff like VC2 or Jeanne d'arc but with NGP changing memory format I'd also have to keep PSP to play them.
