Could be cool both ways. The social aspect is great but you can scale the game up and involve more people by making the dealer a bot. You can still maintain the social part with a chat room.
You can even have a dealer but rather than the dealer record you have a bot do it. Think roulette. The blockchain is the wheel, continously turning. The bot simply records and acts as escrow.. The human dealer could manually input to the bot which block is the one being bet on and simply designate "no more bets" .
