Yes, I'm that guy who doesn't like GTA. Have your laugh and get over it.
Anyway, I was wondering if RDR2 isn't just some 'GTA with cowboys' because it looks fairly interesting (which I also thought of GTA). The game looks good but seems to share some gameplay mechanics from previous Rockstar games. I don't want it to be another Do-whatever-you-want simulator because I prefer an interesting story too.
Red Dead Redemption 2 is an Open World-game, but you can only play the main missions - if you want ;) The game is very detailed. It's definitely one of the best games of the year (my prediction), maybe even the best with Spiderman and God of War.
If you like a big living world with great story, fantastic details, lots of animals, possibilities or cowboys = then yes, enjoy it :) Personally, I'm not a fan of cowboys - but I want to play the game. "Rockstar Games" is known for strong quality :) ps. And it also has an online mode.
"The Last of Us 2" is officially the Game with the most Game of the Year Awards in video game history worldwide, voted by millions Players and Magazines. My Gratulation :) My personally Dream-Game is "Ghost of Tsushima".
