Steam.

The biggest discount may belong to the game you are least likely to play. An example Steam shopping cart shows how checking editions, bundle extras, price history, and available evenings can turn an affordable haul into a couple of worthwhile purchases.

Twenty-five dollars leaves room for several good Steam purchases, even without a sale. Compare baskets for farming, card combinations and sandbox exploration, with the reasons each pairing works—and the point at which buying another cheap game stops helping.
