I'd like to know if it is possible to program games using Flex.
Flex is used a lot for the surrounding GUI of games. Flex is generally not used for the "game loop" portion of games that requires higher performance. This is less true for say a card game then it is for a firts person shooter, of course. Checkout the Push Button Engine. Great platform for building games for the Flash Platform.
