If for nothing else but the ambiance and mood (the somber, and sometimes uplifting music fits well with the game) of the game, I recommend playing this through a few times. Also adds a little historical flavor as well. Towards the end it's pretty tough. I've only managed to get about a 72-hour invasion postpwnment. As agent Smith might have said "it is inevitable" ;)
Yeah I agree; it's a bit glitchy. Funny music though (when its not glitchy) and a creative dev name and game title. I like the little guy in the intro/start screen.
