My suggested edit was rejected because it was too minor. The change I made is indeed technically minor; I just removed the "NWN2" part of the title since it is already included as a tag. While I just removed a few letters from the title, I have always thought that removing "tags" from the question title is not that minor.
Also, if you read the question body, what else is there to correct? It's absolutely fantastic in my opinion. The question is clear, well-researched, and with links even.
Is removing tags from question titles really that minor?
If there is only one small thing that is wrong with a question, should we not bother correcting them then because it is "too minor"?
