I love this.... before the complaints were he didn't have enough people working on the game, now the complaint of the week is that there are a lot of people working on the game.
Hey, guess what, there is a LOT of artwork needed for a game like this. Especially one which is building maps/levels that are 100's of miles in size, and laying out ships alone that are 2+ miles in size, all with internal rooms and systems. That's a ton of 3D modeling and artwork, requiring dozens of artists. Now add in multiple art styles, such as the different human corporations that each have their own esthetic, and multiple races, each with their own unique look, now add a dozen staff writers for backstory/history/lore/language/arts/etc., needed to create a believable universe which has the feel of being old and not just manufactured yesterday.... Add the office workers, IT support staff, maintenance staff, and you easily hit a couple hundred people.
You know how many people worked on Grand Theft Auto 5? According to Rockstar, probably more than 1000... The amount of staff isn't something that you as an outside commentator can have any idea about in terms of it helping or hurting a project. Given that I highly doubt you have access to the current arena commander system (based on the comments made so far about the game and/or lack of progress), I think you should stop bad mouthing a game that you don't even have access to, and thus, have no idea of what its current state is.
