Go out with a bang. Release it, enjoy your 15 minutes in the spotlight, and when the lawyers come a-knocking, shut it down. Or make it open source and let the community take the wheel and the responsibility. You never know what opportunities this adventure might bring, but certainly more than just keeping it on your hard drive. Go for it mate.
I may indeed do this. There is an outstanding issue I have to address that I've never quite worked up the motivation to deal with: Heroku restarts their servers once every 24 hours with only thirty seconds' warning. Since the games are in-memory, this of course kicks everyone out of whatever games they may be in the middle of. I guess the solution is to have the games be on Redis instead of in-memory? I'm a bit more…
Redis would work but I'd be afraid of race conditions. There probably wouldn't be any, but it's something to be aware of.
If you wanted to test the waters with at least the relative public, I'd consider doing step 1 of renting a server, but then hiding it behind a Tor hidden service. Inconvenient to connect to? Yeah. (Probably) safe from the Hasbro demons? Also yeah.
