it is indeed generic, but it's good to see more space games, especially in SPACE STATIONS or space vessels. we don't have many of those. stick in a sci fi skybox, have the level be indoors, but make sure to have a shuttle craft outside the station that you can transport to at some point, so you can see the beautiful vessel or space station
i am planning a game in space as well actually (if you couldnt tell). id like it to be multiplayer, where two vessels fight, their objective being to take over the other vessel. this is my fpsc multiplayer dream, tho i havent tried multi yet, idk if id be able to assign guards for each team (for fpsc multiplayer, its best for LANing, when we'd have say 4 people, 2 manning each ship.. they'd be small ships. id like to assign guards to the security sections, and when the player presses say the BRIDGE button, a group of security personell will move to the bridge, that would be cool. is it possible to have allies/enemies in multiplayer fights?)
or for my non multiplayer, you'd be fighting to keep control of, or take over a, space vessel or space station, with crewmembers or marines by your side
you need to get the details of your story. aliens are trying to use a big space station to destroy earth, and you have to stop them. thats cool, but you need a background for the war right? maybe it is a cosmic diplomatic misunderstanding between two races. you need to know what tech level and what sort of weaponry there will be right? things like that
have fun getting your ideas onto the paper and then the screen!
p.s. girlfriend breakups never "inspire" me to do anything but stay on the couch, and not leave for food, class, or anything. let alone make software. can i examine your brain?
