I think Nemesis in the name is OK, if it gets changed I will start to worry about AT's Nemesis time left...
All it needs is theming and then we could call it Nemesis without any shame, it's underrated.
At least we can think of half decent ride names, so many rides in America are called Goliath...
Chessington should get a Nemesis ride, more similar to Oziris though so it has one thrill ride.
I can picture Nemesis reborn, Nemesis aqua sounds a little stupid. If they though of another Nemesis name related to water, fine by me. Not Nemesis earth because of Sub terra. Nemesis tidal doesn't sound too bad I guess...
