If I'm playing Devil's Advocate - It can be a good idea to have all your major systems in place before really starting on the content, save you realising later down the line that something doesn't work or has to work differently, and having to remake a ton of existing scenes or other things.
I would also say that, if you're in a productive mood, but not for a certain type of work, it may be better to do that, than do something else badly, or do nothing. Like, personally, I write when I'm in a more creative mood (and have the privacy to) and code when I don't have any good writing inspiration (or lack privacy).
I'm gonna be honest though, at this point, I'm more worried that the game's going to have so many potential variables that just making content for it will take a herculean effort. I mean it's nice that they're trying to offer a lot of options, and some of it can be automated, but the sheer bulk of the game seems overwhelming and unwieldy.
Though, I went to play the game to see what content is in the game now (I've played many versions but not for a while) and finish off this post with something of substance, but I've somehow broke it. Or my PC, or something. I sat through a bit of the really long intro, got to making the sex stats, and for some reason had really unfavourable skill point costs. Alright, no back button. Restarted, did it again with a new job, it worked. Saved template, carried on with game. Realised I forgot to set cheats. Restart again, load the template, doesn't work. Load template again, does work. Fucked something else that I now forget, go to restart again, and now it keeps throwing up an error about not being able to load the assets. Nothing moved. I'm starting to feel like this game doesn't want me to play it. Like, it wants to exist, and to grow, but not really do anything.
