Everyone who I hear that runs off and I'm not using this engine BTW so I kind of care for ya hehe.
Anyways everyone I hear running off to another engine and such is now scared of mysql. You have in fact scared people thinking SQL is bad.
We try to please everyone as a developer it gets hard.
Please consider packaging your game with sqlite. If you don't know what it is then please google it. Anyways its perfect for your engine and people who wants to go further and expand they can use mysql. This makes it so people extract run server and it works. Sort of like plug and play. Rather doing the whole installing mysql then installing db and you know.
Anyways consider it and less people will leave and also help stop bring fear into other projects.
Honestly, people who can't be bothered to spend 5 mins setting up mysql, and end up scared of it (????), probably shouldn't be using it anyway.
