There will always be the first version and the subsequent effort, if you really put it. Therefore, it is very important not to discard the games if you have one and only one version. To modify it, fix it, or simply tweak any of the choices to represent an improvement for the game. The version number of the game must be increased. Who wants to stay with Version 1 if you can get Version 3 or Version 4?
Only by insisting on changing the version will the product or game become new, perhaps a game that wants be something serious and insistent, that is there, constantly being updated to provide a better and improved product. This says a lot about yourself and your own game.
