realistic
'Realistic' in terms of visual quality, or financial feasibility?
The game is being built on the Unreal Engine 3 platform, which is a high-end game engine - up there with CryEngine 3
Financially, this project *is*
very ambitious considering that it's a Human-V-Alien multilayer arena (which is very rare for some reason), but with the right careful marketing it may or may not come near or exceed Natural Selection 2.
To give this project high chances, it's going to need a Steam feature for a few weeks, some still advertizing, and at least 2 or 3 good video commercials. Interviewing with game critics and getting a high score on Metacritic will also help a lot.
Which also brings to mind the possibility of utilizing Steam Early Access to raise funding if needed. Murnatan will need more outside attention before then, however... As far as Indie games go, our community is still extremely small when compared to titles like
Nether,
Space Engineers, and
StarForge.
