Is that a custom made mat? Don't think my friend's version has one. We tend to expend outwards further than that though, so maybe that's why we never use it. Actually, surprised the chap playing green didn't want to move out further than he did, that green planty ailen's thing seems to be rapid expansion, or at least that's how I played it.
Went for my gaming night last night. Finally got round to Netrunner (awesome!) and then tried Eclipse for the first time with the Rise of the Ancients expansion. After 4 hours (bearing in mind 3 of us were first timers), this was the table at the end of the night....
