I tried to create tag synonym today for iphone -> ios, since there is an obvious split on these kind of questions. Although true that iOS encompasses the iPhone, iPod Touch and iPad, software that can be run on the iPhone can also run on any of these devices.
However, apparently it requires me to have 5 upvotes on that specific tag. Since we have so many diverse tags as each game gets its own tag, and games that aren't super popular at the moment probably only have one or two questions about them; this means only mods would be able to make the bulk of tag synonyms (as witnessed here).
I thus propose that, at least for gaming, the 5 upvote requirement for creating tag synonyms be removed. Since you already need 2500 reputation to create tag synonyms and there is a voting system in place already - I feel that requiring 5 upvotes seems redundant, or at the very least difficult to achieve at gaming.se.
iphone
tag should be kept separate from anios
tag, as some questions may be specific to the iPhone version of a game (the versions may differ), or may concern the iPhone's hardware exclusively. Of course, these questions could be taggedios
andiphone
.
