Up until a day ago, my $@#%ing sound card hadn't been working for about 6 months after an install.
I FINALLY tracked the problem down to an IRQ setting that was the problem...
So I had been playing CM without sound ever since I d/l'd the demo in February.
After hearing it with sound, I have to say I now think that the immersion level of a game depends largely on the aural experience. Graphics are great, but actually hearing things makes a game come alive.
Hearing the artillery pounding is incredible. Up loud, the 240mm is genuinely terrifying.
Just some thoughts.
