On one hand it's something that makes it feel like you own a game and can actually show it off in the collection and I would love to do it for Bloodstained. On the other hand though I get pissed at companies when they do this kind of thing (original release of Ducktales remastered, Tomb Raider (forget the whole name off the top of my head)) and it also seems like the most unnecessary braggadocio you can do.
Trust me, it has nothing to do with bragging. Lol. Two main reasons for me.
1: Its a tangible, physical representation of something I love. I hate download only titles. Again, I understand when it's some tiny 2-man development team. The vast majority of indies are doing it because they love gaming and without a publisher with money, who can afford to make their own physical games? On the other hand, dirty shit like Capcom, EA & Activision have been pulling where only half of the game is on the disc/cart with a voucher code for the rest is greedy bullshit. It's simply to curb sales of used games and consumers are the ones to get screwed. I would love to have all the Mega Man games on Switch. But I'll be damned if it doesnt piss me off to no end that half of them aren't on the carts. Especially since all 20 (or whatever) Mega Man & X games probably take up 10 megabytes of data total! Same with the Crash & Spyro games. Making you download the 2nd and 3rd games is simply a way to stop people from buying used. Screw these guys.
2: I love artwork. I can stare for hours or spend hours pouring through art books. The game case art was something that an artist worked on for many hours. I like to look at it and it deserves to bee seen.
