RDR 2 is coming in October

I also saw a young John Marston in the trailer.

So far the trailer is 98% cutscenes. There seems to be a few seconds of actual gameplay hidden in there, but I'm not 100% sure.

We knew it'd be a prequel. We saw and heard Dutch. Now we saw Marston.
I'm curious on the new mechanics.

I dread a bare ones single player campaign while the focus is on online. But I can't deny that I'm not excited for it... I  have gone beyond excited...
