look, I was just saying: it's basic common sense when you're making a game to google "GAMENAME game" and see if there is already another game out there called CAMENAME! I'm pretty sure this is Making Anything 101 first day of class type stuff, regardless of your medium/product.
Because if there is already something else out there with the same name as your thing, you're doing neither yourself nor that other developer any favours! <3
Yours Truly,
Someone who still can't believe Hollywood dumbasses made Crash (2004) when Crash (1996) already exists (and is wayyyyy more interesting of a film).
