But maybe the easiest answer to the PHI vs. EXP question is..
I thought you were going to say
That would bring me full circle back to my original choice.
My response was going to then there ^ ^, but you got me thinking....
What the big deal with IMP anyway? I've done 2 test games now. In both, I conquered 7-8 cities, and I could have done more. However, I got lucky with copper in my BFC, so I didn't really need IMP to settle horse/copper. If I do an extra stack of axes instead of several settlers, I'll get 15+ cities by T150.
I was looking forward to settling my own into a nice efficient, low-maintenance empire, but maybe that's just nice-to-have.
My biggest argument for IMP was that I get to
place cities 3 tiles apart. Pack them in from the start, but!...what if I can eliminate that advantage...
Prepare for
your mind to be blown.
(I'm just making this up now as I type, so let's see if I run into any snags)
Once at sushi, exec spread is needed to ~500 cities, right? But, what if the sushi cities did not necessarily include, say, the main 50 cities? What if most are just whipped down to size 1 and given away to the AI? I can only settle 75.9% of the map. Why use all the original cities' area? I already know I have to get
all the islands, then only a portion of the mainland. It's not like I've got a lot of buildings invested in those cities. Likely just a granary. The AI land might have twice as many farms than I have--especially with my plan to use
farming opponents. Just
abandon my start area!
Or, I use the area I start in, but I selectively
raze any city that's not placed well. If it has some food, I use the city for a while. Maybe a long while--all the way the up til Sushi, but I don't waste time spreading an exec there. Since I don't have those nasty Terraces building up culture, I should be able to give some cities to the AI and let them get enough culture so the city is raze-able.
- I'd have to keep certain wonders, but not many.
keep: hangingG, Hagia, Kremlin
give away: oracle, Taj, Paya, MoM, Mids, G.Lighthouse, even HangingG can go after I have enough health from Future tech. even Kremlin eventually (keep until it's obsolete), Colossus after obsolete or in STRIKE mode. GLib. Geez, almost all wonders can be destroyed/gifted. Razing will be tough with all that culture.
I think one problem with this new idea is how to generate sushi execs. The old way uses a combo of whip overflow and/or chop to spread them in a wave around the mainland. Only 1 or 2 per city. (3-4 out of the HQ). Worse case, a city just whips an exec for 2 pop (using kremlin+forge). Not a problem when you have 50+ developed cities that can handle a whip. But now I'm considering only using 10 or 20 of those. A bunch of freshly settled size 1's will not be helpful.
Cities have to be 5 tiles apart or less to spread instantly (pre-railroad. and even after RR, I don't want to waste worker turns on RRs. I want to farm.)
So the problem here is if I have a city 4 or 5 tiles away, I'll often want to raze that one and place cities 3 tiles away and 6 tiles away.
This makes the initial wave of exec spread very complicated.
I think it's doable.
Summary:
I case you didn't follow that, my idea is to
eventually raze and/or permanently gift away a large number of early cities that were poorly settled.
This lessens one of the advantages of IMP. Makes the whole trait more of a nice-to-have.
The challenge is to maintain a nice, efficient, initial sushi spread.
