Apparently someone has no clue what a changelog is supposed to contain or what a walkthrough is.
A
Changelog should contain the alterations made in the program and take 1 to 5 short lines including:
Added X pictures / images / videos
Added Y lines of dialogue or Y words
Edited Z errors (where Z is grammar errors, spelling errors or contextual errors)
A
Walkthrough is greatly appreciated as a separate text or html file that tells you either exactly which actions to perform in what order or approximately which actions you can/should perform for improved game results.
I am not pointing fingers since I don't know who wrote what from the OP but putting a walkthrough in place of the changelog just makes me skip reading the changelog and downloading the game. IF I can read at a glance the 12the update added/altered XYZ content all the way to the first update contained XYZ content, with an obvious change in each short log, I might overlook the Engrish (as many call the machine translation between almost any language to English) and possibly be willing to help by sending the occasional correction. If however, I look at changelog 263 changed/added XYZ with no further changelog (no first upload, 2nd, 3rd, 4th etc...), I won't bother considering a download because you have only made 1 change (this is for any of several games I have seen lately which have only the last changelog included not this specific game).
