"Made With..." Logos are and always have had somewhat of a Bargain Bin association to them., and I'm not just saying AppGameKit but anything that carries such a logo.
Consider that there is an "Unreal Engine" and "Made with Unreal Engine" Splash that can appear in various games., and whenever you see the latter (which is rare today) what kind of "game" are you about to play?
I think you quickly get what I mean.
First Impressions are IMPORTANT., esp. given more and more seek to use AppGameKit to create Commercial Projects.
You don't won't something that comes off like a Junior School Project to be placed on the fridge, saying "I made this with..." but rather you want to simply list the Key Programs in the Introduction Splash Screens that were essentially / associative in Development.
Engine, Art Package, Audio Editor / Engine, Networking Solution, 3rd Party / Contract Studio or Artists, etc.
But more importantly you want it to FEEL Professional.
Something that is a little difficult given AppGameKit itself has a somewhat terrible Logo Design... like don't get me wrong, it's "Fine" from a says what it is standpoint and it's clean., but it's also uninteresting and lacks anything that's eye catching.
There is no associated Symbol that's quickly recognisable., and symbols are a POWERFUL design language... more so when a product title is perhaps a bit wordy and people want a shorthand.
For example consider the Dark BASIC Logo., it was rather eye catching:
This is obviously an updated version as the original was much smaller., and less useful for modern resolutions but the core elements from the original logo are still present.
Now obviously this isn't a Press / Developer Media Kit that would include variations., along with all of the Design Language details that would need to be followed for Custom Logos (such-as Colour Values, Sizes, Spacing, etc.)
For those wondering what such documents look like:

There are various others I have, but most are under Confidential Agreements., so I can't share them... and even this one is arguably old as they just released a new one., but this is still valid for creating logos for various things; such-as the GPU Open / FidelityFX stuff.
But as noted it give you an idea about how these documents are laid out, what they contain, etc.
Again notice the lack of "Made With / On / Using..." and instead just a focus on recognisable branding.
The Game Creators., realistically NEEDS something similar and not something that is hidden but rather is front-and-centre for people to easily add branding to their projects.
