The Xbox One is overflowing with downloadable games lately thanks to the ID@Xbox program. Last week we got Outlast and Sixty Second Shooter Prime, and today Zombie Driver Ultimate Edition had a surprise launch. But when the new console launched last year, players only had a few downloadable games to choose from. The first such title to qualify as a hit was undoubtedly Peggle 2 from Electronic Arts and PopCap. The game later arrived on Xbox 360 as well.
