My favourite flash game ever, well, I would have to go with Dad 'n Me. If you havent played it, you should. You can find it on Newgrounds and its hilariously good! Beating up children has never been so much fun!
After that comes "Paladin The Game" and "Year of the Snake". I like games with good gameplay and grahics and atmosphere is very important as well. Good storylines are a big plus as well, but for Flash games that rarely happens.
The Fancy Pants series is pretty good as well. :)
