Well I was thinking the rules would be,

• No spawning animals
• All animals must be skinned(for proof)
• New Save/Load Save either or -No cheats
• ETC.

I mean Any% killing the animals so I could glitch it to skip story progression and just go right to the area.

Any%? I know of 2 glitches to get past the rivers to Nuevo Paraiso and West Elizabeth, so you don't have to progress through the story. Could I use them?

I was wondering if there could be a misc. section where you have to kill and skin all the animals in RDR.

Can the GBA version be a playable console?
