I'm a UI designer for almost a second decade now. In short textual content is the last thing I need from a site like this. Forgive me but that is just a load of pointless academic pedantry.
I disagree. I've been a UI / UX designer for various pieces of software and the thing I miss in all the collected screenshots online _is_ text. It makes things more easily searchable and comparable. For example, is a health bar vertically or horizontally positioned? Top right or top left? What's the used color?
All these things could show me the obvious choice when designing a health bar in a specific type of game or interface.
No website with screenshot (or otherwise UI based visuals) in collections has this searchable content.
So for me, as a UI designer, I would definitely benefit from more textual information.
I love the design of the site, but the first game I checked is Assasins Creed Black Flag, because I know that game has a very clever UI solution present in at least the early games in the series.
There is nothing in this site about that feature and you cannot explain it with a simple tag. The name "Game UI datase" suggests a bit more than mere tags.
For the interested, the UI solution I was referring to is how the functions of the buttons on the right side of a common joypad are communicated to the player. When one of the buttons is pressed, a short description of all their functions will appear in the top right, layed out in the exact position they have on the actual joypad. Press a modifier key that changes the functionalities of these buttons and their descriptions will change while the modifier key is pressed.
This ensures that you will never forget what all the buttons do, which is a common problem for me as I don't have a lot of time to play and can sometimes leave a game for months before picking it up again.
The website only shows the "empty/unpressed" state of this element of the HUD, skipping one of of it's most innovative features.
Textual content would be used to facilitate searching and to compare the UIs of different game interfaces. For instance, right now, I can't tell what the most common language is for UI buttons in RPGs or see what options are typically available for classic first person shooters without typing it up manually from the screenshots. This would be helpful for non-UI designers who want to make games.
