Since I have been playing mostly New Beginnings, which use the new In Sight procedure, I played a couple test battles of 5150 Star Army to remember the squad-based mechanics. Only then it dawned on me that I would need more figures to properly use the escalating battles system. I already have the extra platoons, tanks and other items printed, I just have to cut and build everything.
Other than that, the 1cm scale felt adequate, especially for solo play. I can play on a small space and even leave the board set up as long as I remember to cover everything with a box lid or something to protect from gusts of wind.
