Full mission list for the first Red Dead Redemption?

Rough order goes New Austin first (Fort Mercer, Bonnie, Armadillo, Seth, Irish, West Dickens), then you cross into Mexico for the whole Nuevo Paraiso section, then West Elizabeth and Blackwater with Edgar Ross, and finally the Beecher's Hope farm missions. After the main ending there's a short bit as Jack too, and that's where the real last mission is. Don't stop at the credits. The menu shows your completion and which stranger missions you've started, which is handy for tracking what you've missed.
