Wasn' the idea of mana in FFVII, I think they called it 'life force' though, right? Anyways, good job planning out your plot before you start writting. I have a few pros/cons about the story from my viewpoint, hope you find them usefull.

Pros.
- Your overall idea of the planets having to work together to escape certain doom....or something of the effect.

Cons.
- For the most part the character(orphaned at an early age) has been overdone several times before. It is honestly hard to write an RPG or most other science fiction without using the 'mysterious character', unknown past or something of the sort but some of the best science fiction has utilized more normal characters (enders game).

- The 'The(insert number between 3 and 13 here) seals protect the sacred (insert building type or geological formation here). This type of device where you can get away with a lot of contact utilizing no story really bothers me, In my opinion its a sign of laziness and almost always turns me off to playing whatever game, and there almost always are in RPGs (lunar silver star story with the armor, grandstream saga with its seals and so on)

anyways, good job on trying, re-editing and taking all criticism well, its often far more usefull then praise. Good luck on your endever.

great! great!!
im glad you're reading the story outline now, thats making the replies much more useful to me. Estok and slowpid: your responses are great and just what i was after! :)
im very happy to say that after seeing your responses, im glad i posted this, and im very happy with the consistent cons being found.
this makes it very easy for me to see whats liked/disliked, and therefore makes it *very* easy to edit. im also happy to see that after reading the outline, everything has fallen in place, and no other questions are being asked about the "what about this" and "this doesnt make sense because" parts of it :)
this is a major piece of information that is extremely useful to me.
now down to the personal responses:
Estok:
im happy to see that after you read the outline, everything began to make sense. as for the sub pars, im happy to say that none of them are exact ideas of mine. ironically though, they are all going to be assumed by most, but thats the way i want it ;) ;) ;) *hint, hint* :)
also the questions you asked were very nice, but i can tell you very safely that i have considered the outcomes and plot twists and i believe that my ideas dont fall into those categories/answers - there is a very large twist planned towards the end which i dont want to share for obvious reasons :) this twist however concerns many of the sub-pars you mentioned and finds (what i think is) a very clever way around it :)...
thanks again for your continued replies. its great to hear constant feedback :)

slowpid:
im not too sure on the ffvii deal (i only really remember the ending bit) so i cant say whether this is like it or not, but i do know that my setting is definately different and provides many new options as to how i can manipulate the story.
pros- just as above, i think this will fit nicely with the game, providing a new experience from other rpgs.
cons- in all honesty, i have been thinking about changing both these parts as well :) like i mentioned a few posts ago, the parents thing has been happily modified (or will be...) to be less expected or different.
the seals part still needs a little work. im going to find a way to work around it because the towers are essential to the rest of the story so i cant really take them out...
thanks for your great suggestions/comments, i can tell you they make me very happy to see that someone else can see the intended idea(s) of the story :)

thanks again to you all for the excellent replies. i cant wait to modify the little bits and get this game under way!
keep an eye out for any updates/screens at your announcements :)
