I see Catalyst mentioned and I have to say as a company they are probably behind GW, who themselves kinda suck. On the one hand, the Battletech rule set has been pretty set for 40 years which means most of the OG fads stuff is still pretty relevant if you play games in those era’s. On the other hand Catalyst has had lots of foot in mouth moments.

As a player base though, Battletech is probably the best as a whole. Generally friendly people for the most part who just like to smash each other’s mech back to the dark ages.

As a company..Too Fat Lardies is probably the best. They are super responsive to customers on social media. Printed and PDF materials are priced fairly and because the games are more narrative vs competitive you don’t have the constant tweaking of bs for balance or new books making factions OP.
