How do you figure?
Version numbering doesn't mean % of the game complete. V0.26 isn't 26% complete. It just means it's the 26th large update since the first (V0.1). With further numbers meaning minor updates to the major update, for example V0.26.1 would likely mean no new content, but bug fixes or something similar.
There are many different version numbering systems different games use, but none of them are counting towards completion, they're simply build numbers to track changes.
