This is what I enjoyed about the first Tribes game. I remember wandering around my base, repairing the generators, placing turrets, fixing sensors, and murdering attackers. The rest of the team would be off grabbing the other teams flag or messing up their base.
IMO the sequels didn't get the balance between base maintenance and flag running quite right.
I dig the role based games where deployables and vehicles are a thing. I'm sure there are still some around, but I can't think of any.
