Hostage Negotiator

This one is recommended by a friend. Since he plays Sentinels of the Multiverse, we're going to assume his judgement is good.

It's called Hostage Negotiator.  It's a solo card game that plays in around 30 minutes and they are into their second Kickstarter.

Check them out.  Tell them Spewgilist sent you.

No one cares.
