After reading some number of reviews, I really doubt free civs would improve reviews:
- Small number of civilizations almost never appear as a reason for negative reviews. Some time ago we had ChatGPT analysis of reviews and this point just wasn't there
- Top reason for bad reviews was UI, but for some reason despite UI being massively improved, reviews didn't become better. It's pretty hard to say what's in people heads
Bad reviews come from a combination of bad impressions, and then the one that floats to the top is the most obvious, which was the half-finished UI.
I think you find more in-depth reviews (like from YTers, game review channels and websites etc.) tend to also complain about the mechanics, and lack of game options (map size), which includes Civ or Leader variety.
I recall some comments on this forum about how euro-centric the Civ choices are for this game.
Plus, we are missing a black male Leader, and also a lot of classic Civ leads - Elizabeth, Genghis, Montezuma, Alexander.
Free Civs could change minds for sure. But they don't need to be free - as long as they came in a big combination pack (NOT sold separately to milk them) - they could then market it as a big comeback for Civ7.
We have 13 right now right?
So let's say they release another 3 per age for a big pack - with 3 new leaders?
Imagine:
Genghis (rep for existing Mongols), Montezuma (classic Rep, paired with Aztecs), and one new Leader.
Antiquity: Goths (Germanic), Huns (Asian), Aztecs (American)
Exploration: Byzantines, Ottomans, and (one American or African Civ)
Modern: Italy, Korea OR South-East Asian Rep, Morocco or Ethiopia.
If you charged £14.99 for that, you'd make a mean profit, and I wouldn't personally say that it's overkill.
People would love heavy hitters and representation from all corners of the world. Plus more militaristic gameplay.
If you had 1 free option for each category additionally then that would appease the remaining people.
