No, not a tirade about the lack of Aluminum Recycling Plants in Civ. Instead, has anyone notice how Firaxis sometimes "recycle" mechanics? I'll give you an example. Trade Route Stacking. Civ VI started with Trade Route stacking, i.e. if you had a Harbour and a Commercial Hub, you got trade routes from both. Coo, cool cool. Nice buff for Coastal Cities, because they inherently get double trade route capacity. And the Harbour and Commercial Hub can sort of synergise. ...but then, disaster. It's too powerful. So, no more stacking. Stop it. No more. You were abusing it, so now it's gone. That's why we can't have nice things people. That's how you get ants. ...anyway. Then trade route stacking comes back as England's super special ability. Yay. But then it goes again. Boo. But now it's back again, but this time as a Super Secret Society Special Bank ability. Yay, again. (Side bar: I much prefer this mechanic being tied to Parliament of Owls Special Freemason Bank, or whatever it is. So, I'm actually pretty happy how this all ended up.) Here's another example. Stacking Regional Bonuses. Civ VI started with allowing Industrial Zone Factories Regional Bonuses to overlap. Coo, cool cool. Lots of production. Oh no, too powerful. Nerf that bad boy. But then stacking bonuses comes back again as Magus' capstone ability. Like, fine, you can stack bonuses. But just for one city, okay! Here's another example. Adjacencies. Harbour give gold adjacency. Shipyards turn that adjacency into Production. Once people really get their heads round that mechanic, people start using it and really enjoying it. Turning one adjacency into another is great fun, because the district sort of gets repurposed, you can play around with policy cards, it gives Cities with unique versions of the district new angles etc. So, here, FXS didn't nerf this mechanic. They just said, yeah, people like that. We should maybe do that some more. So, then they go to town with that mechanic in RnF for dedications. Then they sort of do it again in GS with Coal Plants (albeit its more just doubling IZ adjacencies). Then they do it again with Work Ethic. And now its been given a whole new level with the Secret Society of Bird Watchers unique Bank and the Hermetic Order of Hogwarts Unseen University all using the mechanic. I mean, we're probably at "peak" Adjacency Swapping now, but I really like the implementation of this mechanic in the various ways it's been, er, implemented (although, I could certainly hear the argument for making Work Ethic more like Choral Music and it's bonus based on buildings not adjacencies). So, here's my question. Where have you seen mechanics being recycled and have liked it (or not liked it)? What are some mechanics you think might get recycled again? And what are mechanics you'd like to see recycled. For me, Trade Route Stacking, Regional Bonus Stacking and Adjacencies. I really like all of the examples given above. Particularly the whole adjacencies thing - that's very fun. Build Charges. FXS have gone back to the well a few times with the whole +Extra Build Charge. First it was China and Pyramids and Feudalism. Then Liang. Then England. Again, we're probably now at "peak" extra builder charges, but I really like how this mechanic has been used the various times it comes up. Purple Districts. Maybe not technically "recycling" a mechanic, but I like FXS have implemented another One District Per Civ Government District, i.e. the Diplo Quarter. I think it's a pity both the DQ and GP don't both give +1 Adjacency, and don't both give +1 Envoy next to your City Centre, just because I think the symmetry would be cute. But, yeah, like seeing the basic unique district mechanic getting recycled. Pax Brit. Pax B's original "free melee unit capturing a city" was a pretty cool ability. It then got nerfed inexplicably, and I've never really understood why. England have now been rebalanced in a way that I don't think that ability could ever be brought back for England, but I do think it's found a new life as Zulu's ability to upgrade units to Corps, Armies when they capture cities. I think that's probably a better implementation of the ability, but yeah, there you. One more to think about. Goddess of the Harvest. I think it's likely Goddess of the Harvest (i.e. Faith = Chop Yield) will make a come back, maybe as a Civ ability. GoH was overpowered, but it also allowed for a unique way of playing the game particularly when combined with Monumentality. If FXS could find a way to "balance" the ability, I think they'd be super tempted to bring it back somehow. Work Ethic. I really hope Work Ethics Pop = % Production, Max 15% makes a comeback. I'm not particularly fussed how it comes back. Probably shouldn't come back as an IZ Building Ability or Governor Ability, because that's super boring. Can't be a Government Ability, because that's basically already Communism's ability. Maybe it could be a new ability for some Commercial Hub buildings? Don't care. I don't think it worked as a Religious Belief, but I totally think it could work somewhere else. Thoughts?
