In Mahjongg, one have to go into the preferences dialog to select which variant of the game to play. This is inconsistent with AisleRiot, which has "Select Game" under the Game menu, and also an icon on the toolbar. The AisleRiot method is more discoverable, and more closely associated with the concept of starting a new game. Secondly, they both have the "Fullscreen," "Toolbar," "Hint," "Undo" and "Redo" menu items, but under different menus. For such a simple game, the Preferences dialog might be unnecessary, especially after the game selection dropdown is moved out of it.
