Just finished my first play-through after about 50 hours. No spoilers or hints, and no NPC or player summons except for twice on the Smelter Demon who was kicking my ass. Luckily neither player summon worked and actually seemed to make the boss harder with two players making him move unpredictably. After shelving the game for a while, I came back and one shot him, which seems to be a good plan with these games any time you're too frustrated.
Also I think I missed what looks like four bosses:
Overall I had a lot of fun, but some of my favorite things about the first game weren't really there. I loved the sense of connectivity and openness with Lordran, where you're often given glimpses of different parts of the game world. Basically if you see something in the distance, you know you'll be going there eventually, with multiple paths to get there. Drangleic has that a bit, mostly just in Majula where you can see 3-4 different areas, and occasionally in one area you'll see parts of the next. It basically felt like 3-4 long linear corridors of areas. I suppose it's not a huge deal, but it takes away from the sense of immersion. Also the areas tend to abruptly transition in to totally new types of areas and you get a little texture and atmosphere shock whenever that happens and you think to yourself that no real world would ever work like that. I think Lordran did a great job of setting up area transitions in an interesting and logical manner.
The trash mobs were also just a chore for the most part and were usually far harder than the bosses, unless you just broke down and speed ran past them. In particular
. I think they went overboard there in some spots, though maybe you're supposed to break down and summon help or suck it up and get punished for failing on the bosses.
Anyways, I'm looking forward to trying a magic build now, melee feels a bit too easy on the bosses and too punishing on the trash, I'm curious how range will change things.
