I am really excited about RDR 2. I loved the first geme (well second really but anyway) and Rockstar usually produces a pretty good product.
I can't say that I ever really enjoyed Elder Scrolls online though. I spent some time with it but I lost interest pretty fast. I like the concept of an MMO set in that world but it needs to feel like the same world and I didn't get that. To be fair though, I know there are limits on what can be done in a game of that size and that is probably the source of the shortcomings that I saw in it.
A lot of people are excited over RDR, believe me, I hope it lives up to the hype.
