Let It Ride, Mississippi Stud, Crazy 4, Four Card Poker, 3 Card Baccarat, and I think also Casino War have active patents, while Three Card Poker has an active trademark. They'd have to pay money to get a license for these games.

@Anonymous - Funny you say that as my local casino actually has Mahjong but doesn't offer any of the other games suggested

Other possible games to consider / add are:
3 card poker
Let it ride

Does Casinorpg ever intend to add new games such as Baccarat, Pai Gow, Crazy 4, Omaha, Oklahoma, 4 Card Poker. Casino War, 3 Card Baccarat, and Mississippi Stud.

Mahjongg and Pachinko don't exactly seem like casino games (although the same could be said about Solitaire), while Wheel of Fortune has some huge license concerns.

As much as I appreciate that more casino games would be a great thing, I personally feel it's best to stick to a global approach right now, rather than just small games that not everybody might have heard of, due to fear that a lot of people who don't know those games might not buy them or play them.

More games would be nice :D
