We built a network Tetris game, haha, spent a total of 4 days on it, and very proud of it. Here's the project page. Executables, sources, and full writeups are there, too, and it works! Game is based on Andrew McCarter's single-player title posted at C# Corner.
-Microsoft .NET Runtime version 1.1 (you probably have it already, but if not download here)
- Better single-play, cuz right now it's ugly try-catch around every network exceptions
- A preview screen, so you can know how your opponent is doing
- Better GUI, it's so ugly right now
- Moving the database to my own server instead of the school's :)
Development will resume after final exams week :-P
