I wasn't a huge fan of the first RDR, played through it once and never touched it again. I didn't dislike it, just wasn't impressed.
I just watched the RDR2 trailer, this seems to be a remarkable improvement.
But, I'm still skeptical and not excited because I remember the marketing of GTA5 made it seem there's be many bank robbery missions. And it was a complete dissapointment when I played through the entire game and there was only a few.
Oh, and GTA5's campaign was surprisingly shallow to encourage players to go online and pay for microtransactions, and its pathetic they never released any campaign DLC.
So, Rockstar hasn't lost complete credibility with me, but trust has been violated.
