DS2 is not very linear, at least not enough to start moaning about "the good old days". theres a central town like in demons souls, which has 3-4 exits leading into the world. you can now warp via bonfires which is a nice update. there is still a lot of arriving in a new area and "go left or right, both are completely new areas". sometimes you just hit a wall where everything is taking half your health and you think "eh i should go back to the start and try that other area". you find a lot of locked doors or impassable areas that you'll come back to
eventually you reach the end, and return to the central hub again, like literally every other incarnation of this game. i find some things are now simplified because they were needlessly complicated in the past (like having to find 10 kinds of embers and then 30 kinds of materials, or getting the ability to warp at the last 20% of dark souls 1 lol)
