there is a "practical" single-commander cap for sure, as there is only so much a single commander can do between two ticks. also, as many smaller actions are more effective than single large actions, but we have pretty hard "caps" in place, like ship size or number of profitable commodities, that should always reward group actions.single commander potential, while significant, is limited
as stated before in other threads, i like this aspect of the BGS design. you can work the BGS alone in an Adder and get some results in a small pop low traffic system. You can create quite a bit of more influence shift in a python or cutter. but a player trading in a cutter will still be outclassed by a fleet of adders and sideys, each making 1 8T trade run during lunch time
i often get this question from other players - "i only have a cobra ... can i help at all?"... or "i can only play 2 hours a week, can i help at all?" - and i really like that i can encourage them by saying: your contribution will count a lot. you don't need a huge ship or many hours at hand. that's for me a huge part of the fun playing the BGS in larger groups.
