The stories and characters were the only reason I played any GTA or RDR game though...
I find the gameplay to become repetitive and dull, which is generally the case for action/adventure games like this. Even though Rockstar games are not western RPGs or even Diablo like action RPGs, the inclusion of choice and consequence is something that would normally increase my interest... if it isn't some hippy commie bullshit (like ranking people and choices on their level of perceived oppression). A underworld faction war would be ideal with proper endings for various levels of grey between "good" and "evil" would be ideal.
