I read this great article a while back and was thinking of how something similar could happen with IA. If IA ever died, we as a community could keep it alive. We could vote on regular, new, fan made units and improve and continue the game indefinitely! Cool article too. Never heard of the card game but I love how the players kept it going for so long.

You could have something like 10 fan made candidate deployment cards and easily survey to vote for the top two to add or something.
I'd rather FFG kept putting new stuff out but if they ever stopped...
