Ok, lets see how soon you can come up with an addon which has 800 missions. :)
If you would be a campaign builder like me you would appreciate those addons more. During several years I dont think that I made more than a hundred missions.

Then why paying the cleaner woman, if you own a broom yourself?
You always pay for the time, that you save for yourself, because others spend theirs. Time is the most valuable thing on earth.

Too true.
