Red Dead Redemption for PS3 or XBox 360 for just £20.99.
I, like many invested in a PS3 solely to play GT5 but a friend lent me/bullied me into playing this game, which in fairness I wasn't keen on; Grand Theft Auto but without any cars? It did not sound appealing! But my scepticism was ill-judged to say the least and after about 10 mins playing Red Dead Redemption, I was totally hooked on this game! It's utterly compelling, thus I need a copy of my own!
This is the cheapest I could find this epic game, which is usually around the £25-30 mark from Amazon/Play/Zavvi, etc.
3.5% Quidco available too, which brings the price down to £20.26.
From the manufacturers...
"Red Dead Redemption is an open-world, third-person, action-adventure game set at the tail end of the American West West era. Action takes place in the first few years of the twentieth century and revolves around the choices that the protagonist, former outlaw John Marston, is forced to make due to his blemished past. The game features a morality system assigning honor and fame points generated through the player's choices. It also features Wild West themed mini-games, new targeting and cover systems, extensive horse riding abilities, a wealth of period specific weapons and more than 40 huntable animals."
