Sega doesn’t fit any of those buckets. No consistency except that they’re not consistent. You don’t know what a Sega title will bring. Like they rotate management every week.

Yeah this is a result of Sega's management strategy where all the employees line up outside in the morning along one of the business obstacle courses. Whoever can run through the course fastest and collect the most coins gets to be CEO for the day. Is it chaotic and ableist? Yeah sure, but it does ensure that if a bear attacked the office that Sega employees would be well trained to deal with the emergency. Also, it isn't THAT much less efficient than having utterly useless out of touch CEOs running the company who don't give a shit about their customers or the artistic merit of what they are making. At least with this system sometimes the good thing happens amid all the chaos.

Does Sega spend inordinate amounts of money on building elaborate obstacle courses that have nothing to do with their core products? Yes, but remember all that money and more would just be going to CEO bonuses and stock buybacks for investors at a normal large company, building obstacle courses is comparatively a much more efficient and equitable way to allocate profits (not to mention there is a much smaller carbon footprint to building obstacle courses vs. yachts).
