Sony played the part of the genie and answered three longstanding wishes. Which apparently was not enough to overcome the hype for backwards compatibility starting with: A Kingdom for Keflings, A World for Keflings, Alien Hominid HD, Banjo-Kazooie, Banjo-Tooie, BattleBlock Theater, Defense Grid, Geometry Wars Evolved, Hexic HD, Jetpac Refuelled, Kameo, Mass Effect, N+, Perfect Dark, Perfect Dark Zero, Small Arms, Super Meat Boy, Toy Soldiers, Toy Soldiers Cold War, Viva Piñata, Viva Piñata TIP & Zuma.
I'm honestly baffled by the whole thing, but then again, Pokemon & CoD both became huge and I was left similarly confused by the tastes of fellow gamers.
