Here they are side-by-side.
Sample of Civ7's features:
- Holy cities can be converted
This is a feature? Are you sure this is not just a tweak?
- Naval units can disperse IP city.
Okay this is just another basic tweak.
- Customize names of Cities
Wow revolutionary, I think we had this in Civ1.
- Research queueing
Why is this even 3 updates out from the start of the roadmap?
The most major updates are all in the 'More To Come' section, which doesn't really help sell it.
Even so, most of those were in previous titles, like Auto-Explore, Hotseat, Map sizes and shapes.
When it comes to Ara, we can point out only 2 or 3 minor features - like 'AI city settling improvements'.
Other than that they have substantial improvements every month. At the end, they promise, with a date, a 'Major Design Update' and 'New User Experience'.
So I mean to me, the Ara roadmap showcases far more active and diligent development, promising tons of improvements everywhere, heavy new content simultaneously, and even new free content for all players.
The Civ roadmap showcases minor polish and improvements.
