This session illuminates valuable lessons developers have learned in designing and implementing mechanics for contemporary cross-platform RPGs. Though classic RPGs have their roots in simulating tabletop games, recent titles such as Dragon Age, Mass Effect, Fallout 3 and New Vegas, Alpha Protocol, and Dungeon Siege 3 commonly borrow more player-driven mechanics from other genres. From the pitfalls of virtual die rolls to the challenges of balancing player skill with character statistics, the session breaks down what works, what doesn't, and why RPG fans are often their own worst enemies.
