I think a lot of people will realise sometime next year that 2016 has too many games to buy and way too many to play... ROTR is supposedly coming out next holidays. This is the same time roughly that Horizon is meant to be released and its more direct competitor Uncharted 4 will have been released for almost 6 months. I think the adventure itch will well and truly have been scratched. Horizon looks to me to be one of the most promising games in years and I really cant wait to play it. If it came down to the two games, I think most would go with Horizon. Not to mention they have a load of toys and memorabilia to go with it. Looks like it will be big!
