A few of us are just getting started with Blkout and I'm wondering about scenarios. Most of those in the rulebook specify a 2x2 board (I don't have any expansion content yet). Are most people playing on this size, playing these scenarios on a 3x3, or playing different scenarios?

As a secondary question, are any of the expansions better for scenario content? We don't need the rules on new unit types yet, and I only want to get one or two for now.

Thanks!
