But what does it have to do with naming?
Update 7 was split into "update 7 part 1" and "update 7 part 2"
What is there not to understand about it?
The size of the update and the name don't really mix. What people care about is the size of the update and how long it took to come. Making "parts" of 0.0x is stupid.. it's like slicing pizza when it was already sliced. His updates aren't game expansions big games have. Usually when you see "part1" you expect "part2" to come out relatively soon, but if it comes out same as regular update then what's the point of naming it in parts? Imo it's just stupid.
YOUR expectations don't have to concur with reality. If a "soon" release was possible, why split at all?
"people" also have expectations from the main version number. BB had certain things implemented in version 6, people here expect about the same story progrss things to be in version 6 in BBAS. They want similar things in version 9 as the original had. If we now shift all version numbers, people will complain about THAT.
Software versions are usually split into 4 groups of numbers, what you call 'stupid' is the standard.
You could have had it simple. Ignore part 1 completely, stay with 0.6 and wait until 0.7 is finished. But you chose to play part 1, now live with it.
And really ... is the naming of a game version the one thing that bothers you most about this game? Then I am glad you enjoy it so much.
