Getting wasted, €???

Counter Strike 1.6, 5$, 1000+ hours.

Playing with shopping carts at the mall's empty parking lot when I was younger... Good times I spent there. It was free, with the drawback of having to run away when security approached.

Binding of Isaac.

Humble Voxatron Debute for $1, came with Binding of Isaac and Blocks That Matter. BTM is one of my all time favorite games, and I had never heard of it before Voxatron.
