One of the extensions I really look forward to the most, is the connection to Google Game Service. I'll definitely use the trophy system. But there's one problem, and in preparation for the extension it might be nice to exchange some ideas.
I also want to make online high scores available and I'm sure many have the same idea. However, just to test, I hacked some games I have. The sad thing is that it's relatively easy. Even with games made by big brands like EA's Monopoly you can root your phone and with a few clicks make yourself a billionaire and your opponent bankrupt. You input a value like score or money in a hacking app, you change the value in-game and input that as well, the app recognizes the hex the value is connected to and you can simply edit the value to whatever you like.
Only a few other games made it pretty impossible (at least for me), or they patched the holes away over time. SimCity crashes for instance when you modify hex during the game. Even if there is one very difficult possibility to mess around with scores in-game it completely destroys the charm of online high scores.
Does anyone have an idea to protect yourself against it? I'm pretty sceptical since so many games by big companies can be hacked so easily.
