Regarding mobile games... I'm heavily into a corker of a Java3D game by the name of PlanetRider.... very similar to Wipeout... but on your mobile phone and in lovely smooth 3D.

If you like you fruit machines, well this site is to Fruit machines as MAME is to arcade games!! All your best machines... using REAL roms from the machines so they act and work EXACTLY as the machines would in an arcade/Casino
