Question for #boardgame and #wargame  folks… I want to play various old games online via android tablets with some old game droogs.
-We want to play mostly one on one so peer to peer is in the mix.
-Setting up a server is not a problem, I have a box here at home I use for game servers.
-Some of the games we want to play are not popular, supported or available on the devices we want to play them on. One or two of them are games we have developed ourselves, so it would need to have the ability to load in game assets.
-It would need to be able to save states so we can makes moves at our own pace. 
Think of something like #cyberboard   or #VASSL   but for android   and you are in the right area. Any thoughts on the apps that might be able to do this?  
(Yep we tried G+ Hangouts on the desktop  to do some of this and it was less than optimal)
