Those of you who like the game, do you also like the part about era transition where gameplay elements are destroyed, repositioned or downgraded? Just asking, because I fail to imagine how can this be fun in any possible way. Or maybe this is not true, just invented by malicious reviewers?
Yeah, I enjoy it generally. It isn't my favorite thing about the game. Getting a whole new set of some combination of units, improvements, buildings, mechanics, and civic tree is cool. The tradition policies from your previous civ(s) are a cool way to make new synergies that can sometimes be very powerful. You always have access to your current civ's unique stuff, instead of having to wait until later in the game or only have them be useful in the early game.
There are downsides too. As you reach the end of an age you may not feel like creating buildings that you are only going to get the benefit of for a short time. Having cities revert to towns can suck, but there is a way out of having to do that.
I'm not a stickler for thoughts like "NO, Incans can't turn into French, it makes no sense!". I think that drives a lot of the negative reviews. I don't play civ to be an actual real world historical simulator. I play it to have fun. So if middle ages China ends up becoming modern Mexico, and I can't emphasize this enough, I DO NOT CARE, IT'S A VIDEOGAME. It's a fantasy 4X game with historical references.
Ok done ranting. Age resets aren't the greatest feature ever but the game is good, especially with patches and mods. Anyone who says the age change makes everything you did pointless is lying, or they haven't played much. The UI is bad and the game has a godawful learning curve. Not because it's incredibly complex, it's not, but it refuses to tell you how certain aspects work. The civilopedia is worthless. It took me over a week to play my first game because I was asking questions online and looking up how to play far more than actually playing.
Once it clicks for you, you'll like it, as long as the ahistorical stuff doesn't bother you. It has the potential to be the greatest civ game ever in my opinion.
