Hmm.
Do you mean the current planned storyline, or the ideas I threw out, off the cuff? (Which raises the question : How does realism figure in a sci-fi game dealing with aliens invading a future earth, but that is a whole different kettle of fish, no?)
Is there even a current planned storyline?
I found this on the site :
"What we as a team wanted to make is a brand new experience that tries to surpass the quality of games from 1992, rather than simply recreate them with flashier graphics. "
Well, I guess what I was trying to get at with the previous post was that what's missing is a game-world, built up around the game.
For instance, in planescape torment (and pretty much all the best games I've ever played), or even sci-fi movies (eg star trek, star wars) an entire game universe has been created and the game / movie "fits" into the universe. (with the exception of star wars episodes iv v and vi which... sucked) The universe includes things that would normally happen, outside of the immediate context. political relationships, interpersonal relationships, backstories etcetc
At the moment, with what the game presents, what I see (from the user-end) is a combat interface and geoscape interface, with an unfolding tech tree.
The entire backstory is unidimensional, and deals exclusively with how we humans ended up going from present day to the redefined political borders that exist in the game - up to the point of alien contact.
The story pretty much halts there, and so far I haven't learnt anything about who the aliens are and what they want, much less why there are so many different shapes of aliens but they all want the same thing, which is... err... to shoot at my troops, and any civilians they happen to be standing near to.
X-com had a little more story in that we knew why the aliens were here - they were harvesting human beings for parts. We never really found out what that was about either.
the UFO series of games had some strange biomass thing going, which as the games advanced proved to be a force for remodelling earth into a new alien haven. We never did find out much about who the aliens were either, and the games generally felt very flat.
With movies like star trek, a large amount of effort has gone into writing a behind the scenes story so that things feel... real. We know that different alien governments exist, each has relationships between themselves, and nothing is absolutely black and white. Different aliens behave differently, all have their own motives, some exist in conferations (humans) or collectives (like the borg), yet others are just angry and trigger happy (eg romulans) etcetc.
Does this make sense?
