It used to be the Holy Grail of every gamer I knew: the "arcade perfect" console game. Well, Sega's Crazy Taxi was the game that made me feel I had finally found that legendary chalice.
Was it a rather superficial affair, with a limited amount of replay value? Sure, you could argue that. Of course, it was addictive as all get-out, too, which helped draw things out a bit.
The point of this post isn't to make a case for Crazy Taxi being one of the greatest games ever made, though--hell, I don't even necessarily think it's a great game. It is a great port of an arcade game, though, and that was more than enough for me back in the day.
