I saw it twice too! *dances* Second time in imax, which was awesome

Fantasy World:

Runes aiding potion making would be cool. And I can imagine they'd have to be careful, for example some ingredients wouldn't mix with some aspects and could cause explosions (especially if fire is involved) so only the most skilled use runes to tamper with potions?

Sci-fi:

AI yay! xD Gotta love some AI... I have slight rudimentary knowledge about AI. But yes, holographic stuff would be so cool and fun! Communication would be very easy and the like. And yeah short-range teleportation works, probably quite rare though as its still being worked on? Definitely still new... So most of the people with them are almost test subjects to check if they work? So malfunctions and stuff. Though it could be interesting if someone with a cybertech limb went to one of the other worlds and it just stopped working

Modern World:

2014-15 would definitely work, I think, as it doesn't really involve much research and just makes things simpler. 

Misc:

Sounds good! No ideas from me (I'm just waiting for that spark of inspiration to come)

I quite like Earth, Thera and Rathe. The sound quite cool and actually I don't seem like rearrangements of earth at first glance. I like them. 

I like the idea two. And 20-30s works for me! I mean definitely good in terms of experience and gives so much more options for skills of characters and the like. Only so much a teenager knows really. And 3-4 paragraphs per character is fine for me, I should be able to do that for two characters. Any more and maybe it'd need to be slightly shorter but that suits me!

Ah, good... I sometimes feel like I'm slacking but I try you know :)
