Well, really to Tabletop Wargaming generally. I brought the Beginner Box Set 35020 with some printed record sheets from flechssheets because I'm not brave enough to write on the cards it comes with. We grabbed extra minis from our D&D piles.
We played GRF-1N (PPC,LRM10) and WLV-6M (LL, 2ML)
Versus
GRF-1S (LL, 2ML, LRM5) and WLV-6R (AC5, SRM6, ML)
They agreed that criticals and physical attacks sounded fun, so we added those rules. No heat, though they thought it would be a fun addition for next time. We played on one included map sheet with some trees but no elevation.
They were frustrated by how often they missed, and how slim the to-hit usually was. (Aiming for 10+ most of the time. Once they got better at managing their movement, the game got more fun. I jumped around a bit and told them anecdotes from past games and lore tidbits. Once we got to start rolling clusters and criticals they got into it, trying to get side and rear facing shots.
It was fun, and they are willing to play again, but they were dismayedthat it took three hours. Maybe I should finally learn to play Alpha Strike. I have the book but not the box set yet.
