Let's see what previous changelogs have looked like:
Hmm, you know, it seems to mention just how much stuff was added since the previous version, sometimes even in absolutes. Usually however, it's nice when a dev says exactly what bugs were fixed and whatnot, such as "Bug fixed when player does XYZ." Stuff like that is always nice to see, and really shows how far a game has come.
However, stuff like "stuff", "more story", or even "N/A" is not nice to see, because how do I determine whether I should even bother with this version, or if last version was fine to keep? See, I have not downloaded this game before, but if I come to like it, how do I determine whether I should even bother with an upcoming version, or if I should just ignore it and move on?
