For movies, we recommend VLC player. It's free and will play almost anything. As for the game, you'll have to figure that one out on your own. There's a good chance it won't even work, as there are many fake programs on the Gnutella network. Be sure and scan the file(s) with an antivirus program before opening. MOST program files are fake, infected, or freeware/shareware.

P.S. Try looking for the answer yourself next time. This question has been asked many, many times before. Also, you posted in a thread about music. Next time, start your own thread. Just letting you know.
