Having backed some projects i freaking agree.
I backed WAS , grisaia and others.
I liked the idea of someone trying to bring something new to the table ( even bought WEE1 )
But damn if they need to talk more to keep their fans invested.
People will understand if there are unexpected problems, that shit happens everytime. i'm now sadder each i see more project to show supports when i need more info on the project i've already supported.
I'm worried that they try to take more than they can manage and that we get nothing in the end.
Andi say this as someone who has fault, WEE, grisaia , WAs ( and more ) in their expectations since i've supported them about those projects.
While I agree that the communication can be better, it's felt like they were trying to do a bit more than they can handle for quite a while now. SP has mentioned that they've been expanding and hiring on their forums, but you don't want to hire help too late either.
For example, shipping and logistics for physical goods (especially internationally) is a huge problem for everyone and there are so many possible forms to fill out or automate.
I would like some more things said to keep the marketing interest up (which they really need to do) and that's for sure. The VN scene could use all of the new faces that it can get.
I think Sekai Project has been a bit overly optimistic about completion dates and it puts communication into a very awkward situation at times. I'm also not thrilled that they haven't given customers more information about the goods they are selling through BackerKit (or at least not getting further along with them before closing them) sometimes too. The cutoff for The Human Reignition Project is very weird given that fact.
Still, all that said, they are a younger company and companies have to learn how to do things just like everyone else. I would be amazed if they weren't selling the Kickstarter exclusive Clannad physical at a loss (EDIT: maybe not but it wouldn't be much gain). What they have done so far is GREAT in many ways. They need to remind everyone that it is by keeping up with information about important things, and not just to questions on their forums. These products can only market themselves so much, and customers should expect reasonable things such as "we're alive".
