Microservice strategy? Store per service or combine?

I’m pretty new to event sourcing and I’m curious what the strategy is with microservices using the CQRS model. Normally, I’d expect each service to have its own physical database, but I’m not seeing the ability to have multiple stores in EventStore (maybe I missed it?). So do I have a separate instance of EventStore for each service? I don’t much like the idea of sharing the same store between services.
