Well good luck trying to convince your audience they are all wrong. I can even predict the outcome.And they do it wrong, so that's their problem if they don't even bother to search any info about that.
But it is not me who you wan't to convince about using common naming rules - I'm totally agree with that system.There is no rule book for this and you can pick whatever method you want.
But usually the first number only represents the version, "0" means an early version, pre-release or Alpha/Beta test version, "1" means a post release or final version, a "2" would represent major changes in the game mechanics and redesign from the previous version.
The second number represents an update, it could be anything from new mechanics to additional content but never something that goes as far as to change the core of the game to make look like something new.
And the third number is for fixes without adding anything new to the game (both this and the second number can also be called a Patch by the way, what would make it even more confusing by using that wording instead ).
You are joking, right? Adequate devs have design document, which is in worst case scenario covers about 60% of major content, from the beginning to the end, except maybe minor details like sidestories or additional mechanics. To see how much progress they've made they just have to look into that document ad see what was implemented and what was not.No it simple doesn't make any sense that the dev(s) have to predict the future so they can name each version until the final release is a way they can then release all content in a balanced quantity to not confuse the poor costumers and it makes even less sense that they need to create more content out of nowher because the are now at version 0.42.0 and they are still missing 48 versions to reach v1.0.
If you don't like the numbers then don't bother with them.
If there is no such document, then the development process bacame a shitty mess without any actual chance to succeed(regardles of what devs can say). You can see dozens of examples right here, on this site.
