Wait, what do you mean about the pity system? It’s identical for between Genshin, Star Rail, and Zenless.

I think it’s, what, like 90 for 5 star, 10 for 4 star. Standard and Limited banner tracks their own counter. Pulling on one doesn’t reset the other.

Armies in 5 and 6 are kind of underwhelming. Maybe a compromise of having terrain have unit capacities, with various units taking up more space.

They were also much simpler and smaller back then with often extremely limited specification variations. And DRM existed back then too, with some fairly egregious and infamous physical DRM checks.
