The first few games I played were 4 players. Two teams just playing 100 or 150 points. We just looked through the cards and picked what looked fun without knowing much about it. We had a good time. I learned the details later once I bought into the game.
Alright, I guess I'll just do squads myself then and just pick the most basic stuff, with straightforward mechanics, while having some theme at the same time (such as Luke).
