I tried the demo of "The Great Escape" That game is doomed. Even if in the final version they fix all the bugs from the demo, and improve graphics, gameplay still sucks. Game totally failed to impress me. I'd like to see the movie though.
Next I tried the demo of Deadly Dozen, a squad based shooter. You can commaned your squad with the keyboard, however, I haven't had the chance to try that in actual combat in the demo. Graphics are nice, you get to drive some vehicles and try out a lot of weapons, both Allied and German. Apart from the unrealistic number of weapons you can carry, and their weight-lemme see you carry 2 bazookas and still run around- the game was actually fun and challenging.
