If its for a review on the forum, take a popular game, but that no one made. But if its on the comment box of a game, then choose the newest one. (that the only one in were the mods check).
gotta agree with you there atleast in terms of it being a great game personally I don't care about replay value in a game I play it once till I beat it give up or get sick of it then I look for something new.... unfortunately that gets harder and harder the more games I play even when I don't play flash games for months at a time and come back its rare theres more than 3 or 4 new games that seem worth playing
