Yeah, I'd like to see this in action first and I'm curious how it will handle future expansion packs (if it can be expanded like PC version) but if this is the true game, I'd get it for Switch. First time Civilization is back on a Nintendo console since the first one and the SNES. There was Civilization Revolution but that was more a spin-off / separate entry. I always though Civ 3 would work well on the DS but that never happened.
By the time the Direct airs there is not going to be any surprises left.
