Red Dead Redemption

Red Dead Redemption features an open-world environment for players to
explore, including frontier towns, rolling prairies teaming with
wildlife, and perilous mountain passes - each packed with an endless
flow of varied distractions. Along the way, players will experience the
heat of gunfights and battles, meet a host of unique characters,
struggle against the harshness of one of the worlds last remaining
wildernesses, and ultimately pick their own precarious path through an
epic story about the death of the Wild West and the gunslingers that
inhabited it.
