A new report from SuperData (via GamesIndustry) has put Riot Games' popular and lucrative free-to-play MOBA title League of Legends' revenue for 2013 at $624 million, a huge income win for the company.

Oddly enough though, SuperData notes that this wasn't the highest grossing title of 2013, with that win going to CrossFire, an online shooter from the South Korean developer SmileGate that earned $957 million. Other noteworthy contenders include Blizzard, which earned $213 million from microtransactions alone, a sizeable chunk considering it still requires users to pay a monthly sub fee to play.

In related League of Legends news, reports are coming in from the UK forums that some users are experiencing issues in trying to download the game's patches thanks to the UK’s new anti-porn filter (thanks VG247).

According to a forum post, the problem seems to be stemming from somewhat unfortunately named variables that include the word "sex", something that the new filter picks up instantly and blocks without question. Those in question include “VarusExpirationTimer.luaobj” and “XerathMageChainsExtended.luaobj”.

While the obvious question is why exactly a filter is so overzealous as to ban the word sex, users have reported that solutions include getting a friend to download the patch, opting out of the filter or whitelisting the files.
