Main thing I love with sub terra's story line? Two things:
- It's a slightly feasible idea. It feels like it really could happen, more so than most rides
- You have a reason to be there. You can get some great storylines on some high budget rides, but not many have a sense of why you are in this situation. Even with nemesis, it's difficult to guess this.
I am sad it closed. I only did it twice, and it was about a week before it finally closed. Absolutely terrified the first time I did it (tried to do oblivion, ripsaw and NST for the first time all in one day, that was interesting), but liked it so much I ran round and did it again.
