idle han:I'd recomend using a 'working title'. A games plot / essence could change dramatically during its development so that your starting name might become inappropirate for the game. - or worse, unfashionable by the time of its completion!
Working titles can also become finalized titles! :)
Last year I was taking an Advanced Game Programming class, and had planned to make an open-world racing game, with the twist of allowing players to drive on any surface (including upside-down). Of course, with only one semester to produce something playable that also looked nice, the fact that we couldn't even get our physics working correctly for 2 weeks sucked. (Note also, that this was the first time I or either of my partners had been writing code for a 3D game; our models looked awesome, though - one of my two partners had experience working on models for
X-COM)
So, we fell to a backup plan game. It was a kind of sandbox, space pirate game (think
Sid Meier's Pirates! Live the Life, in space). Our working title for it was "Backup Plan", and it just ended up fitting the final product pretty well :)
