In the StarCraft errata there is this paragraph:

"Team Game Restriction
When playing a team game, a player cannot build a base on a planetif it will cause his team to have a base on every area of the planet. This is to prevent a team from acquiring the air support module and making it impossible for opponents to move to a small planet."

So... In the light of the new Offensive Module , does this ruling still stand in Brood War ?

I would say, rule it yourself in your group. I would say no.

Fact is that it's not very common for this situation to happen. Anyway, I still have problem dealing with teamwork in this game.

Well, I kinda love making bottlenecks. It's one of the most powerful defense strategies. So I think it's pretty important to know for sure how to handle this particular situation from now on.

...and I tend to agree with Stefan
