One of those games that you get attached to..
I loved Asteriods! I'd still play it now although I don't think that I've got the cartridge anymore because it's so old..
I'd sit there for hours trying to get to the top of the high score table...
I've recently been playing an online version of the game, and I sat on the game for 2 hours straight without Game Over, and I got 225,000 points, just so I could reach the top of the highscore table online.
That shows how much of a determined gamer I am :P
Anyways, this is one of the 'old-skool' games, or the 'on the way to the airport' games.
