before i commit my self to my big project...i want to find out what will be better to use AS2 or AS3, i am more comfortable with AS2 but AS3 is a powerful and performs actions much quicker, however simple things in AS2 like Key.isDown has been transformed to much harder EventListner Functions, also senior members on this forum perfer using AS2 rather than AS3.

The game will be like a fighting game, similar to street fighter and tekken games, there will be loads of different characters and different moves, also the user can select different armours and sword, move sets, e.g. a character can equip a fire move set, armours and fire sword....so which should i use AS2 or AS3?
