What's everyone playing at the moment?

I'm an entry level penoid as it stands, with only Carcassone and Catan to my name. My friend has recently got a few which have been good (Ticket to Ride, Small World, Chinatown, Sushi Go, Pandemic), so I'm in the market for different ones to bring to the table.

I'm liking the look of Munchkin, Race for the Galaxy and Dominion. Any other recommendations? If anyone can vouch for Munchkin a lot I'll probably buy it tomorrow. Is the Deluxe edition worth it?
