Release to Marketplace Complete

I was able to achieve my recent goal of listing on the UE4 Marketplace.
What I released is a Code Plugin called ObjectDeliverer.
It’s priced as Free, so anyone can use it.

It’s primarily a library for inter-process communication between UE4 applications and other applications.
It might not be a perfect match for those using UE4 for game development, but I think it will resonate with those using it for other purposes and wanting to link with other applications.
I myself am currently using it for content creation utilizing VR.
I have written separate articles about this library, so please take a look if you are interested.

History Leading Up to Release
Just in case, I’ll jot down how things went leading up to the release.
2018/12
Thought of writing a communication library for UE4 and started working on it. Decided to aim for a Marketplace release while I was at it.
2019/1
Completed the first version of the library. Tested it by using it myself. Fixed all the bugs found.
2019/2/7
Learned that packaging is necessary for Marketplace submission, researched → implemented.

2019/2/10
Registered as a seller on the Marketplace and registered the created package. Completed everything while feeling anxious about whether the entries were correct.
The email after registration stated it would take 15 to 20 business days for the review to complete.

2019/2/16
Received an email saying it would be reviewed within 5 business days.
Was a bit surprised as I was prepared to wait for about a month.
2019/2/18
The review was finished, and some minor corrections were needed.
Specifically, I was pointed out to add a Copyright notice at the beginning of the C++ source files.
Also, I was asked to describe the MarketplaceURL in the *.uplugin file and re-register the file.
Implemented the corrections and re-registered on the same day.
2019/2/19
Received notification that it would proceed to the final review within 3 to 5 business days.
2019/2/19
Received an email just before the date changed, stating the status had become APPROVED. It said I just needed to log into my product page myself and change the status to PUBLISHED.
Did it immediately, and the release was successfully completed.
Checked on the Epic Games Launcher, and it was indeed there!!

Managed to Release by Trying Hard
It had been years since I last released an iOS app to any store, so it was a lot of fun.
Above all, there’s a sense of accomplishment.
The review, which I thought would take a long time, ended up taking only 10 days, so the wait was totally bearable, and more importantly, I was relieved it wasn’t rejected.
Thank you to the Epic staff who reviewed it.
That said, releasing a library to the store can be considered the start, so I want to maintain it properly.
I still have 2 or 3 more ideas in my head, so it would be great if I could release again.
