As far as the strategy cake description goes:
Simple, fun and lighthearted, but it also highlights your deep understanding of FPS's...FPS's can be these big cinematic experiences with set piece moments and several other gimmicks and sometimes they're fun, but at their core, FPS's are composed of primarily immersion, AI and other factors such as level design, fun factor that are standard in many other genres. Showing that you understand the basis of all first person shooters conveys what you're trying to do with Interstellar Marines. It's not trying to be this new first person shooter with really cool features that no one has ever seen before, it's trying to expand on what is already there, innovating where it has to but mostly improving the core traits of FPS's to make something that is feels like it has been done before, but ALSO feels COMPLETELY fresh and new.
It doesn't contain elements of fanboyism or bias either and it emphasises your love for games as well.
As far as AAA Indie itself, I think we all get it. ^^
