Hi there, I wanted to comment on this,
“Scaleform Studio” which comes with Stingray does not use flash anymore and has its own editor to set up the graphics/timelines/logic and it uses Lua to code the UI logic/interaction so you don’t use the flash editor to set up anymore and there is no actionscript running so no overhead issues that would come along with that. I’ve attached an image of Scaleform Studio.
Also about WWise Wise is included with Stingray, so no additional licensing is needed to use Wwise in your game.
Cheers,
Remi
