Yes, and the game attempts to model this (given that any game that needs to gamify systems, your opinion on how well they succeed at this will be different to mine). It's why you can have buildings from previous Ages in your current Age. Previously, we only had Wonders (in VI).
Like sure, criticise this, but previous games did this
worse, so.
Yeah, that's fair. For me, I like getting through to a victory. However, I am not a skilled player (never have been), so I tend to check out when my victory seems impossible. Which, as it happens, is an embarrassing amount of the time
I also dislike the tedium that seems to come with lategame systems and micromanagement. I'm hoping Exploration and Modern can get to the point where they feel as tight / well-designed as Antiquity. I have a blast in Antiquity.
