Its very intertaining, super imersive, looks amazing (the scenary in this game is mind blowing) but its heavy on the controlls, gameplay could be a lot more fluid. It basicaly controll as heavyly as The Witcher series has always controlled, I was hopping theyd have fixed that in this one, this can eb (and already is) and isue for some ppl, I dont mind it too much.
About the leveling up speed, the game has infinite content basically, if it was easy to lv up youd be on lv 60 (the cap) after like 10 hours of play cause of all the stuf you can do on this game. Dont grind by killing monsters either, do quests and side objectives (like monsters nests, liberating settlements, finding hiden treasures etc).
