and to add to that, i doubt there will be a physical release from the start, so pushing the release back dnf style won't do much except screw up with people's expectations.
it'll probably be a digital release at first with bugfixes, patches and dlc as it's completed, and once all that is finished, fixed and ready, then they will release the completed version in physical form, which will probably come in 2019 to 2020. wouldn't make sense to release physical as soon as they're done, and then while digital backers get to play first, physical backers wait for days, even weeks for their copy to arrive just to get day one patches which defeats the purpose of physical copy being independent from internet. sending a second, complete phys copy once it's all finished would make even less sense from financial perspective.
digital to play as it comes out not to be left out, physical for collection and future when/if the console online stores ever go offline as part of planned obsolescence. there's no actual difference between phys and digital gameplay wise except maybe longer loading times for physical.
No Man's Sky is still garbage but its insane how mainstream give it another chance due to the update it got like how long after its intial launch? and despite its bad reputation and shady business, it now has spiked interest and more buying it, which is ridiculous.
but anyways the point is, they could release the core game of Bloodstained ROTN campaign, then add more to it over time with patches/DLC etc. to rekindle interest long after the game has launched.
so I think from a business standpoint, ROTN devs may resort to staggered content release style, especially considering interest in the game is waning and people just wanna play the story campaign already. especially in these days, DLC and add ons and patches are common, so people are likely to get more interested in the game and could get a larger fanbase if it gets updated and new modes/content from the stretch goals over time.
and yea, even Friday the 13th the game launched digital, then this year got a physical release.
nothing wrong with Bloodstained ROTN getting milked, a lot of prosperous companies do those things and a lot of people buy into those sort of business models.
PC patching and post launch content culture has spilled onto consoles, so expecting full content definitive version games day 1 is really not that common overall.
sure a lot would like the full game with all the stretch goals include, but they could release a later edition like MK does with all the DLC addons they add through the months. people double dip in game editions a lot, especially if its from a favorite IP.
well yea they could push it to later, though that could affect morale. Im not sure how Code Vein will be received after its been delayed, well it could do better, but I dunno about Bloodstained ROTN.
the devs have the backers to think of too. a lot of them want to play the full game while they are still breathing.
