Okay, so I blame Lost for this last night, but I was watching them play Risk and it makes me want to play it again. From what I've seen, the best version of this is Lux Delux, which has a linux version, but its commercial/ not open-source. Besides that I'm pretty sure it uses a Java VM.

Barring that, I found this list which has 3 other clones. Would it be possible for someone to port these over for Maemo?
