Negative: Civ7 is right now a bit too simplistic, i didn't find hidden gameplay, some theorycrafting will be needed but so far, playing diplomatic and getting city-states seems really overpowered imho (especially against AI, i would guess that MP make the game more interesting), and the IA is still shit at military (Civ5 VP really put the bar high, but this is worse than 6). Map generation is as broken as it was for civ6, perhaps worse. The "realism" make its hard to differentiate buildings, and the town/city mechanic are really weird (civpedia is here though)

Positive: The new way units and general work is great, i like the sim possibilities with the way building and specialists work (even though the UI is really getting in the way imho). The "souvenirs" (sorry don't have the translation) mechanic is a really good idea for solo play, the game is really, really stable (more than Civ6 and half of paradox games), i want to try a MP game with someone from South Africa or australia to see if the MP stability issues are still present in 7 (maybe MPH won't be necessary now). Civpedia is as usual, great.

Overall: if you really like civ-like 4X (humankind, endless space, or even millenia), especially solo, you should try it now. If you don't, wait a bit. If you like those, but like competitive multi, wait a bit (it's not as unbalanced as Civ6 was on launch, but close i would say). I'd say that for a new 4X player, it's better to play civ7 than civ6

Check the Steam page for reviews. Seems like the consensus is that a lot of the game mechanics were stripped out so they could be sold as DLCs.

Verdict is that core gameplay is a big improvement and a lot of fun, but the UI gets in the way too much. High price and questionable DRM make this a "wait for sale", maybe after some expansions/DLCs land or at least after the first patch next month.

These days it's usually better to try and find players on youtube or twitch than to read text based reviews.

Eurogamer gave it a 2/5.

They basically said "it looks good and sounds good but it is just dull"

I found this one to be quite impartial: https://www.youtube.com/watch?v=B67vadCC1gg
