Sega today announced vague plans to pull certain mobile games that no longer meet its standards, though it isn't saying which games will be affected.

　　"At Sega we are committed to making fun, high-quality mobile games and it is with our fans' best playing experience in mind that we announce the removal of a number of games from our back catalog," Sega said in a post on its blog. "It is important for us to ensure that all of our fans, regardless of platform or operating system, have a great playing experience and after evaluating our complete list of titles, we have determined that a number of them no longer meet our standards."

　　Crazy Taxi: City Rush, one of Sega's mobile games (though not necessarily one set to be removed)Due to this, the offending games will be pulled in the "next few weeks" from the iOS App Store, Google Play Store, Amazon App Store, and Samsung App Store.

　　As for what those games will be, Sega isn't saying just yet. Whatever they might be, the company hasn't ruled out the possibility of re-releasing them in the future, perhaps with these standards-breaking issues resolved. "While we have nothing to announce at this time, given the right situation, these titles may return in an updated form," the company said.

　　Should you already own any of the games that get pulled, you won't be affected. You'll be able to continue playing, and they'll remain in your download history so they can be re-downloaded if you decide to delete them. It doesn't sound as if they'll be updated to support future OS updates, however, as Sega notes you'll be able to re-download and play "until the game becomes incompatible with the latest phone operating systems or hardware."

　　Sega has a fairly extensive collection of mobile games that consists of a mix of original games (Crazy Taxi: City Rush, Kingdom Conquest II) and ports of multiplatform games (everything from classic Sonic games to Phantasy Star to Sonic All-Stars Racing).
