"Visually, Redemption is spectacular - you could easily just smoke a joint and watch Marston ride around the changing landscape, taking in canyons, buttes and rolling plains as orange sunrise morphs into purple sunset. Game engineers motion-captured horses to replicate their movement as accurately as that of the human characters. Rockstar built an ecosystem in which you can eat the wild plants, and wind and weather change randomly, affecting events as they unspool. Redemption used more than 500 voice actors and features 14 hours of original music broken into dynamic stems that respond to actions and events. The game even features the first-ever digital lasso, which is impressive because curved, fluid objects like rope where impossible to render on any game systems before PS3 and Xbox 360. Estimates put the game's development cost somewhere between $60 million and $100 million. (Rockstar has no comment on the budget.)"
