Thanks for the replies, guys! It's fascinating to hear that there have already been a handful of developers utilizing game development tools in other areas aside from gaming. This pushes me more to explore creating the app I have in mind.
What do you hope to gain with this question I wonder? Just to know that someone has already done it, or is there something more specific you are wondering about?
Not really sure what I hoped to gain, sorry, but I was mostly just curious if there are people who have used libraries and frameworks made for gaming in ways totally unrelated to gaming
Thanks for the FYI! Nice to know about this, but I'm not looking for a web-based solution for now. I'm planning to create a simple desktop app to use at work.
