Game Frontends have come to Android in a big way in the last couple of months. There is Nostalgia, Gamesome and XBMC (via either the Advanced Launcher or RCB plugins). Links below if you're interested. Just like PC Frontends need command lines, Android frontends need Action Intents and I was wondering if the Android port of AGS will add these so it too can have games launched directly from a frontend.
