Red Dead Redemption has a decent amount of wildlife. Diversed and quite immersive, it however lacked a deeper immersion.
For instance, I'd love to see trappers, foot hunters doing their job in the forests and meadows. That'd be awesome to meet a couple of hunters, while wandering in the vast forests of the game.
We could have a better RPG component: for instance, having a true economy with the inclusion of a ranch, that the player could own and manage. Pelts, meat and stuff could be harvested and sold to the rest of the open world. You could make profits from it. It's a bit like an Assassin's Creed 3 fashion, which was great.
As for animals, there was enough variety in RDR but it could be further expanded with the inclusion of black bears (very common across the USA), or even orignals (maybe in thee northernmost locations).
What do you guys think?
