Supply/Demand
Quantity/Quality
Bang for Buck
My views:
If you want an LE of anything then execute.
Buy what you want if/when it's on the market as it's drying up as a whole.
Buy Quality over Quantity makes your buys more enjoyable and liquid (asset).
As a whole I've stuck with games from $600-$2000 range, bang for buck out of my games has made me happy!
