I organize LAN for my friend group (from 10 to 16 people). We play mostly CS:GO and UT2004. We tried Xonotic but it didn't catch on. Sometimes we play OverWatch, but the 6 players limit hurt. Also Aoe2 and War3 when we are in a RTS mood. I would love to find a fun car game (something in the vein of Burnout 3). I tried to introduce SuperTuxCard, but my picky friends didn't like it. We are not into moba, nor battle royal game. Any recommendations worth looking?
Perhaps Reflex Area is for you. There's also this Reddit thread with some ideas:

Edit: and recording actions so you can do some hi-def video recording later.
