Very. I was up at 3am conquering Vanu bases while they slept. Suddenly, BAM. They somehow regroup and take OUR home base. Our offensive turned into a 2 hour defense.
But we managed to hang on by a thread, thanks to me. I was the only one repairing base defense turrets. The only one!
The game is great. You can find you and your army fighting off 50 Vanu plebs when suddenly the Terran Republic n00bs decide to horn in on the fun and BAM! 3-way cluster -blam!-.
