I'm broke :( but owning artbooks of my favorite games have always been goals for me, so hopefully once my financial situation allows it! (But honestly I might go crazy and buy too many books lol)
I have a few hard copies, while the digital one I get them from everyone sharing theirs here (I'm really grateful). Sometimes I even collect artbooks from games I don't even play, like Bloodborne. It's amazing to see the creativity, from the various character concept designs to the director's commentary on specific scenes. I love looking through them, and they serve as great references.
I am definitely going through the artbook after I am done with game.
Once I looked through the art book before completing the game and got spoiled about one of the characters... Never repeating the same mistake
I enjoy looking through artbooks, especially when they include design drafts and commentary. It's always interesting to see which characters the designer nailed immediately and which characters changed a dozen times before the official design was settled.
Yes, absolutely! There are so many artists whose work I adore, such as Kazuki Yone, Miko, Usuba Kageroo, Hanamura Mai etc. I own some artbooks, some of them are more... collection of works of a certain artist while others more game-focused.
For works I really enjoy, yes. Like always I enjoy full content than missing content from my favourites. Extra artworks, and sketches etc what's there not to like?
