So I think almost anyone that like Fallout and has an interest in mobile gaming (at least on Android) has discovered that you can play Fallout 1/2/T on mobile devices via an emulator such as DosBox Turbo, however the results are resource intensive and buggy.
So it's a simple question really: would you like to see the classic Fallout games come to Android/iOS/Windows Phone natively?
Personally I'd love it. While I rarely play classics when I'm sat at home on my PC (because I've got many newer titles I'm still catching up with) when I'm out and about being able to play ten minutes of a classic game on my phone in a lunch break is a pleasure. Being able to play Fallout on my phone in a reliable, comfortable way would make me very happy.
