Pong had a better ending[/QUOTE]
I don't know if I'd personally go that far, but I'll admit that the ending really turned me away from the series as a whole. I used to love it to death and even replayed the end mission of 2 more than a few times just to hype myself up for whatever came next - and when that whatever finally happened, well... I was more than a little let down. Haven't felt the urge to play any of the games since then, since, as you all know, the ending of 3 doesn't really hinge on anything you did throughout the rest of the series.
Rant aside, I'd still say the series as a whole is worth the ~$25-30 you can pay for all three if you shop around.
