Custom Tiers

The Kickstarter rewards are not a merch store. You may upgrade your tier, but not pick and choose only the things you want. If that was the case, there would be no incentive to pledge more to get the next tier. Plus, Fangamer spent a lot of time making that backer survey. I seriously doubt they could dedicate the resources to changing it again. If you only want one certain item, perhaps you can buy it off eBay after the game is out.

It would take too much time to take care of each backer anyway.

Can I get a Runic Forging Discount Version where I just maybe name something? :V

I don't see it happening for a lot of the stuff. The soundtrack is the best chance. The art book? Maybe. The map? I can easily see something like that being specially produced so basically having the kickstarter numbers will let them know how many they have to make. Really, if you want the map you're probably going to have to upgrade to the 500 tier.

There's only one fundraiser I can kinda remember that let you pick add on a to add to your choice. And that was only for beta access, the soundtrack, a shirt or the art book. None of the bigger stuff was available.

Fangamer has a merchandise page for a few things. Maybe we'll see Bloodstained stuff on there after its release.

If they wanted to make, like, a new and different shirt/poster/ect. post launch I'd find that reasonable. But if I see someone wearing the backer-shirt or go to someone's home and see the backer-poster on their wall, it should be an instant sign that "hey, that person backed the project years ago". Same with the Whip-Sword in-game. That item should never be made available to non-backers. If you're doing online co-op and the other player is using the Whip-Sword it should bring the "hey, that player was a backer".

Can't agree on the Whip-Sword. Physical exclusives, sure. But in-game exclusive content bothers me, especially when it's tied into any sort of pre-order deal(and for the purposes of in-game content, I'll include crowd-funding in that definition). Make it DLC, part of a more expensive collector's edition or whatever, but no one should be locked out of part of the game because they didn't show up to the party at the right time.

I will grant that the best way to do this likely would have been to never include in-game content for backers-only to begin with, but it has, and how its handled from here has a few things to be considered:
-People are already upset about it: "A boss and weapon should not be exclusive content, it should be in the base game for everyone" is the argument of course, and its a perfectly valid one to use. 

So lets say its made into DLC: $5 for the boss and weapon to be added to the game, which we'll put at a reasonable $40 retail. Maybe less, maybe more, who knows.
-non-backers will still be angry that they have to pay for something that "should be in the base game"
-Now at least a few Backers will be angry that something that had until-then been just for them, is being sold to everyone. "I paid good money to get my special joke boss and weapon, it should stay that way"

Giving it out as DLC could actually make the situation worse, unless its just flat out free, which would then go back to "why isnt it in the base game if you dont even have to pay for it" Plus, I think we'd all feel cheated if the content we went in for was just handed out for nothing: We'd have essentially spent extra just for the slipcover. Which I know I and probably others would feel is worth the extra cash, that goes back into physical goods, but I think we can all agree some Backers would not be pleased. 

I don't see that as being as big an issue as there being content that people who bought the game can't get at all. Non-base content for collector's editions has been a thing since at least Baldur's Gate 2, and extra DLC content is pretty much standard now(e.g. there was no big uproar about the Mass Effect weapon pack DLC). Most of the fuss these days gets made about stuff like the Goro being pre-order only for Mortal Kombat X and other such exclusive pre-order bonuses. That's the sort of situation that is just crap for anyone who misses out, and for good reason. It's not the sort of controversy I'd want Bloodstained caught up in.
