It’s fun to play.
-You don’t slow down to a snails pace at camps.
-Shooting and general movement is fluid.
-There are a lot more weapons to pick from.
-The motorcycle is a ton of fun to ride, especially when upgraded. (Better than a horse IMO)
-It’s completely open, you can go inside every building.
-The weather is amazing, with snow and rain that accumulates.
-You can play how you want, you can even gather a freaker horde and direct them towards enemy camps and watch the onslaught from a safe distance.
-The world is alive, even travelling from one location to another can be dangerous
-There are tons of dynamic events
-There are numerous enemy types you can even find them clash at random, freaker, marauder, wildlife, reapers, different types of freakers will even fight other freakers
-The music is sublime
There’s probably other areas I’m forgetting, graphics are arguably better but some prefer the cartoony look of RDR2 over the realistic look of Days Gone.
