Thanks. That was an interesting read coming from someone who has spent well over 500 (fumbling) hours on DaS with a fair amount of experience in DeS. But yes, despite being one of my favourite games of all time DaS certainly isn't particularly approachable for a lot of people which is a shame since it's one incredibly deep experience. While it does rely on exploring things yourself it does a poor job at explaining some basic mechanics like weapon scaling or humanity. From what I've heard they're trying to make the sequel more accessible but just as challenging with the same emphasis on exploring.
On a side note DaS is a great game because it takes full advantage of all the facets of being a game like a unique multiplayer system and heavy storytelling through environments and story telling among many other things. Structurally DaS also strongly resembles Castlevania Symphony of The Night (another of my personal favourites) so that's worth checking out too. I could say a lot more about DaS but I could easily write a book on this if I were to go off the chain.
I will however, plug this podcast though which talks about DaS in a book club style. Worth a listen if you spend most of your non-DaS time thinking about it, which I do a lot since it came out.
