Hey Acamp, why can't I post on your wall anymore? It's like...gone.
I've probably replayed Red Dead more than any of Rockstar's other games. It's kind of fun just starting from scratch and making different choices during some missions, or being evil and killing more innocents on a different game file. I remember spending hours and hours trying to get the Mo van Barr wanted poster to show up in Armadillo so I could unlock the Deadly Assassin Outfit that came with my preorder...fucker would never show up, no matter what I did. Spent hours on that, then came to find out it was a bug. I ended up starting a new game file from scratch rather than wait for Rockstar to fix it.
I did find a neat little trick/glitch, don't know if Rockstar ever fixed it or not. You can get early access to West Elizabeth, which unlocks all kinds of fun goodies for you early in the game. It gets you access to some of the best guns, allows you to hunt high paying critters like bears and buffalo, you can tame an American Standardbred (Horse with the fastest top speed in the game), and plenty of other things. I put the tip up on Gamefaqs, looks like it's still there.
