I've been thinking of using node.js as a backend for an online game. Does anyone know if it is viable or games that have used it?

  It's viable. Drivers exist for most of the interesting storage engines you'd use for user records, leaderboards and the like. You'll need to pay attention to any server-side operations that require heavy CPU and ensure those tasks don't block time-critical operations. You may or may not get the same level of concurrency as someone's custom-tuned C++ backend, but you won't have to pay an arm and a leg to license it, either. :)
