ElderScrolls games we've already covered our guides for Skyrim and Oblivion have been out for ages:

SimCity - I wrote a guide myself - not complete:

League of Legends we have good material for that over on mmofan, it would probably make sense for me to transfer that over to SuperCheats. The problem with MMO games are they really take a dedicated writer to continually keep the guide up to date, if we could find a good writer to take that on we'd consider covering it... We do pay for all guides so they would get cash for it.
