Art books are always worth it
Yeah, I already have quite a few artbooks & history books related to gaming, mainly Udon or imported, but thing with artbooks is I usually look through them once (though slowly so I can appreciate everything & read all the comments), then put them on the shelf & forget about them/don't read them again for a while. Though I feel like they work better as coffee table books because you see them & decide to pick it up because you don't have anything else to do at the moment, and it's more visible/ready to pick up compared to on the shelf.
I got about 4 Udon artbooks (Breath of Fire, Darkstalkers, Marvel Vs. Capcom, & Mega Man 25th + MMX), plus a few other gaming books (History of Sonic, Every Day is Play, History of Nintendo 1889 - 1980, Before Mario, Mega Drive/Genesis Collected Works, Hardcore Gaming 101, etc.) that're more a mixture of art/pictures & history/text. Heck, I've been tempted to make a thread in Gaming about these kinds of books. If I get an artbook, I'd like it to have pictures I just can't easily find on Google. I like behind-the-scenes stuff, concept art, story boards, unused concepts, comments on how they came up with stuff, etc. I wanna learn about the art I'm seeing.
There's also one on Summer Wars, which I might get in the future. Now that I have an actual income again, I'm more open to getting those books compared to before when I'd focus my money on games....though not this month or Oct. because of how many damn games are coming out.
I might get the Persona 4 one (& Arena), but I feel like waiting to see if they make updated versions for Golden & Ultimax.
