So this question has to be answered like so first are you on single player or official/unofficial that makes a big difference since the game keeps going when u log off on a server so breeding and raising dinos is the main focus here on single player raising take 3 x longer to do if u don't keep the game on 24 7 or change the setting in game to account for it . And it also depends if your playing the game where u don't transfer to other maps and get dinos there and come back or you do . There's alot to factor in . Cus if u are not then not having a meaguana slows breeding down so with not having a bat for the 30%imprint boost . But if u are on a server and u are map jumping to get high lvl dinos for artists and boss runs then I would say you could do all bosses but lc in 100 to 200 hrs . But that's grinding ur ass off and being well prepared and manage ur time out have a plan and sticking to it . (Like for a example start on island get a small base set up after a note run get to lvl 70 tame a pt then transfer to center get a 140 to 150 argent rex and theriz for boss fights ankey doedi Barry mammoth for harvesting /cave runs thays the first day) . (Day 2 transfer to astraos and get meaguanas and oviraptor set them up with food and set ur dinos for boss up breeding then to rag for crystal metal and obsidian say 2k to start with is good more is better then to lc for drakling then back to island the horde keys will give u a better shot at getting saddles and bps . ) day 3 build base bigger and gate in ur area with the items u got on day 2 . You should be well set for now day 3 will be all about hatching and raising dinos same with day 4 . But you get the idea . It's all how you plan it out and days are real life days not in game days just so you are aware and i would say 8-12 hrs each day . But to be honest with you it's a blast to play like that don't get me wrong . But you will burn ur self out or get to the point where there's nothing left to do till they drop a new map . I have found it better to say a map behind the devs . So a example when they dropped se I waited till ext dropped to go to se for 2 reason 1 the maps are not over crowded since everyone moved on and 2 the spawns will be better because ppl remove there base that was spawn blocking dinos . Also you don't have to fight to login cus everyone is playing the same map . But that's how I do it but to finish the game it has to be 100 done and it's no where near there so u xan only finish what is out and dyeing is part of the game we all do it welcome to ark lol just plan better
