OK, I found a new game called "Left 4 Dead" and I bought both 1 and 2 for $30. I was playing the first one for a few hours with NO problem. I enjoyed the single player campaign with the three other bots they gave me. It was really easy but I was into smashing zombies.
Then I installed a mod for Left 4 Dead 2. You would think that a company like Valve would ensure consistency of performance of their product as well as the graphic quality and gameplay. Well, with these titles, Valve gets 2/3. Both games CRASH for reasons completely unknown to me. There I am playing for about three hours and I'm about to get into a really exciting buildup to a last battle before ...
... blank screen.
As the windows startup little song comes on, my anger builds until ... well I now no longer have a mug that says "good dude" anymore.
The following motivational poster shows how frustrated I am in a company that I KNOW prides itself on quality and positive fastidious level design.
