Before starting to play for the first time you'll have the option to download as many language packs as you want from the many different ones the game has. That said, downloading the dictionaries (which you have to do for the game to work properly) can take a bit of time.
Once you have the language packs it's easy to start playing with a friend on either a local network or the same computer, or against the computer. Keep in mind, in any case, that the computer is quite powerful and might always end up winning.
Scrabble3D is brilliant for lovers of this famous board game, who'll find several game modes, several views and a very simple and smooth interface where you can enjoy a quick game with no problems.
