Crawlers are a pain in the neck. I don't really mind them as long as I don't have to look after them, so you can put those nitros back to your pocket Archaic.

The bonus, which *is* huge, I admit, is simply not worth the required micromanagement IMHO. When I play SP, I want to enjoy myself, and that seldom includes hordes of crawlers. I am a hopeless micromanager when it comes to formers though. Maybe I should just try the little buggers out again some day. :shrugs:
My lack of experience in the crawler department is the prime reason why I don't do much multiplaying.
I am not sure if I'll become a team member though. I have a little idea, which may be a bit difficult to execute, but I may want to give it a shot. It has nothing to do with faction choices or game mechanics, so I will keep it a secret.
