I love a good stupid game and I would bet that many of you do as well. I have wasted my time having semi-fun at www.albinoblacksheep.com It's not the coolest thing in the world, but most of the games reminded me of that helicopter game. Note: These games are only for those that enjoy wasting time.
One of my favorites ever was not an online game, it was on contained within MS DOS 5.0 (I believe, or maybe the one just prior). It was in qbasic and it was called Gorillas. You had 2 King Kong looking gorillas who threw bannanas at each other (over a building, judging wind direction and speed) and when you hit the other player, he would blow up.
I remember that game! I used to play it all the time back in this one high school computer class I had... Snakebyte on the ole' Apple IIE also kicked ass... my favorite online game is probable that mini putt game...the one with the arrows that made the ball go in that direction really fast
