I keep on fluctuating between Nemesis and Oblivion. There's more substance to Nemesis, from the entire presentation to a stunning first half of a coaster. I know it dies after the "over the station zero-g", but I'm usually in such a great mood from the ride that I don't care too much :lol:
Oblivion is just too short, but it's a perfect blast of thrill. I just adore the drop, it's really like nothing else, such a shame it ends there, but... If there was more, it would probably dilute the feeling from the drop and make it a weaker overall ride.
So the two always swap places for me, simply because both are flawed, but enjoyable rides.
