People sometimes gets crazy about making mini-games with flash.
The Murlog RPG is one good example.
Take wow gamestyle and GFX, put it in 2D and make an RPG game with incredible graphics and long gameplay (you can even save the game). Talents, levels, items and treasures...
If you like RPGs you should try, but if you like Wow you must try it.
