Huge Ship Brawl is a variant I discovered in the GenCon Events list. Since I had a conflict and couldn't attend it, I tried it at home.
Rules: Same as regular Epic except it's 150 points per side and you're only allowed to use Huge Ships.
I wanted to give this a glowing recommendation as I finished a game in 2 hours. It's worth noting that this included EVERYTHING, unpacking, setup, no one conceded - my Corvette was fully destroyed, and breakdown and packing up. In my experience, 300+ point games take a day, while this was done in a single evening! Even though I got my butt kicked, I had a lot of fun and got to bust out my CR90. Totally worth it!
