Looks good. Honestly it looks like how I remember RDR to look like, as I thought it was the most gorgeous world to roam around at the time, but seeing screens of RDR these days it doesn't look all that pretty, the graphics are dated. So RDR2 brings the environments back up to nice looking wilderness again.
Definitely stoked for it. Don't even care about the story/missions though I hope they're good. With RDR I just really enjoyed hanging out in a nice looking wilderness sandbox world riding horses. It's been enough years that I could totally go for doing that again. Plus hey, canoes now!
