You love Sega because they can no longer hurt you.
That's a thesis statement on the way Sega romanticizing functions. I choose to say romanticizing rather than nostalgia because much of this is as much from people who didn't or couldn't have grown up with their consoles. It is easier to romanticize what the company was in its glory days now when the facts of how they operated are simply history. It's easy to look back and arrange a history "this would have been really cool if it had had any take up" a beautiful vision of a past that could have been rather than living with how actually programming on the hardware was a unique circle of hell if you weren't a huge optimization grognard or how when the ill-conceived product of an R&D team with too much money inevitably sputtered out some kid was holding the 400 dollar bag.
