This is probably the game of the decade so far, and worth playing. Not just playing, getting into and doing everything. However it's pretty hard at first. There are plenty of tools to help you as you get further along and most of it isn't bad at all outside of a few major hiccup bosses (most of which are optional). So don't be scared off by reviewers calling it "inaccessible".
All of that said, it's a Fromsoft game and they can be an acquired taste. Lot of people, myself included, hated their first Fromsoft game for the first 5-10 hours. Why is this so slow? Why is there a delay on my attacks? Why can't I run into a crowd of mobs and maul them?
So if this is your first Fromsoft game get ready for that 5-10 hour "adjustment phase" where you WTF a lot at the game until it subconsciously clicks and you know what it wants from you. Once you get through that phase and "get" Fromsoft, then you have this entire game open to you plus 5 other incredible games they've made over the past decade and a half (Demon Souls, Dark Souls 1-3, Bloodborne). I seriously envy anybody who gets to play all these for the first time.
