In every campaign i played in last 8 years, my brother buys one of these as soon as his character can afford it. Then he does "pimp my carriage" and adds stuff to it.
if you can imagine that being towed by a pair of giant hamsters, thats how I imagined the wagons of Orbril the Gnomes Grand Circus Maximus
I'm more for Pillars 2, where you have mobile HQ.Like the one to beat for me is the Pillars of Eternity castle: Caed Nua. You get it: you rebuild it from its ruins and build amenities; you have a massive megadungeon underneth that led to its ruin; you have people showing up asking for help; the former owners claim rights; and when the legal case goes in your favour, he raises an army. That's a full campaign in itself.
