And where did I say that? I am saying, deleting the app or cache, without wiping all game data from SD card can and will still prevent you from booting the game.

And if you have a game account, like username and password, your account is stored on mobage servers, you can delete app, change phones or whatever as long you know your login info. You wont lose your account.

The data on your phone that app made are sometimes corrupted, thats why they prevent the app from starting, and sadly, deleting cache using settings is just a first step, app leaves a lot of data on SD card, i installed other games from mobage and deleted them all, still had 900mb of data in mobage folder along with over 9000 files, that slowed anything to a crawl.
