However, the tag name simcity doesn't give the impression it would apply to a specific game in the series. I've seen a few posts mistakenly using simcity, rather than using the correct game-specific tag like simcity-3000 or simcity-buildit.
sonic-the-hedgehog-2006 and tomb-raider-2013 are other examples of games where the tag name differs from the official name. Not to mention simcity-classic, which was named SimCity when it was released.
The reason for this is that if someone enters simcity and it turns into simcity-2013, then they know that they are doing the wrong thing if they meant simcity-3000 or simcity-buildit. And the suggestions will show the specific tags rather than the synonym. So people will have to manually type in the whole word rather than just enough to get the suggestion.
I don't think it should be renamed. Not that I wouldn't prefer it that way, but because officially the title is SimCity, and it's even like that in the Box Art.
That comes in contrast with other SimCity games such as Sim City 2000 (1993), Sim City 3000 (1999) or my personal favourite Sim City 4 (2003). And of course the Original SimCity Classic (1989) whose original name was simply SimCity, but was renamed afterwards.
We should be striving to make tags as clear as possible, and officially SimCity refers to SimCity (2013). What we can do is create a simcity-series if it's really needed to have an abragent tag.
Overall, I do believe that we should keep the same, because that's what the game is officially called.
