Ultimately, gamers should get what they expect from a game, according to its genre. From a puzzle, racing or sports game: unlimited replayability. From a shooter: multiple hours of rip-roaring action. From RPGs: weeks of glazy-eyed stat-boosting. From The Sims: the usual load of micromanaging bollocks. It's all about quality of content, as Bill Gardner says. And a full-price game should rightfully have more quality content than any other medium out there.
