Topic on Talk:List of PC games with features removed compared to their console versions
"Missing" is always a problematic moving goal post that is ultimately unachievable, which is why PCGW generally has not considered or taking that sort of thing into account.
Updating lists like this or game articles to state that X original PC version doesn't include Y or Z features in re-releases serves little purpose. It is also made more problematic when dealing with games that have multiple releases on PC.
The original version of Final Fantasy 7 has like three different releases on PC -- is it really worth stating on all three of them their missing features compared to consoles versions released at a much later point when the earlier PC versions weren't even regarded as "current"?
Focusing on "removed" allows us to create a timeless article properly categorize PC versions missing features compared to their direct console equivalent without having to go back and update older entires once covered.
