Good idea, but not enough.
The most disappointing thing about the pub games is the game Skinnerbox. The slot machine game is ridiculous because there is no skill needed on the gamers side. Atleast in the other games you have to choose to continue playing or how much to bet. But in Skinnerbox all you do is mash the A button.
The best thing about the games are the 15 items that you can unlock by playing the tournaments. Especially the 5 star items because they will not be able to be bought in the game. Therefore there was a reason to buy the Pub games and to play them.
