And I've beaten the game. Looks like it took me just under 25 hours total. I ended up spending some time learning to parry in order to beat ol' Gwyn (hadn't parried at all pretty much the whole game up to that point) but I got him eventually. Glad there was a "proper" final boss in this game unlike Demon's (though I of course realize the end boss of Boletarian Palace is pretty much the end boss).
So yeah, overall I enjoyed it a good bit more than Demon's Souls. The one thing I'd say I preferred was the Nexus+level select setup they had going. Ironically it felt more open than the open world, because you never felt stuck on a path like I did sometimes in Dark (IE you CAN go to a different area, but if you're already at a bonfire before warping/that you can't warp back to you feel kind of pressured to stick to that branch till you finish it). Other than that, stuff like no encumbrance and the Estus Flasks did a lot for me. And I'm really, really glad they figured out implementing shortcuts more thoroughly. I mean, the beginning of Boletarian Palace in Demon's showed great promise, but then the kind of dropped the ball on shortcuts for the rest of the game. Though I will say that I really wish they would've given better routes here for all the lord souls bosses.
Though I will say it's a bit of a shame that a lot of the bosses really can't handle it too well when you hug close and strafe. I actually think I may have liked Demon's collection of bosses a tad better. I weirdly don't feel there was anything quite as impressive as the Tower Knight or that giant fire demon (which to be fair I don't recall being quite as good as it was on paper, but at least it certainly left one heck of an impression). Also, I just want to say that most of the bosses got me kind of into Monster Hunter mode. They actually have a bit of a weirdly similar feel there.
Anyway, I had a good time with the game for sure, though I think I'll take a nice break from it rather than doing DLC or New Game+ or any of that stuff, as I'm feeling pretty satisfied for now. Maybe I'll take another year break before picking up/digging into the sequel, like I did from Demon's to Dark. This stuff is enjoyable, but it kind of wears me down, haha.
