I've seen others bring up the way Great War Bombers (GWB, bombers) have changed their place in Acken's mod. A quick
search of this thread for simply "bombers" shows quite a few posts (
I doubt this link will work). And my games so far have been similar experiences.
I think Acken's mod has exposed a bit of poor game design in the BNW tech tree that is obscured in the base game. Here are some thoughts on how this has come about (I'm sure others will have their own interpretations, and am looking forward to hearing how terribly wrong I am).
Science Surge
In BNW we're all accustomed to timing our social policies around Rationalism being in the Renaissance. I'll hold off on a culture push if I'm close but not quite to the Renaissance, and I'll change my research to begin the Renaissance earlier if possible before an upcoming policy adoption. But of course the AI presumably doesn't do this so their tech rate doesn't accelerate as hard as the player's in the Renaissance-Industrial eras.
Of course play style, the game's difficulty level, and how a particular game has developed will alter specifically when a player overtakes the AI in research but after playing some Acken's Mod I realize in hindsight that sometime during BNW's Industrial era is... well it's when I get lazy. In my very first Acken's game I had to recall my spies from rigging elections back to stealing techs when I realized the top AI had kept pace with me.
Counters: Rock, Paper, Scissors
Horsemen are an early Classical era unit on the "middle" path of the tech tree, but their Spearmen counter comes earlier in the late Ancient era and is on the "lower" path. If you and your opponent are researching the middle path you both get horsemen and you're both matched. If instead you take the lower path they'll have horsemen before you but you'll still have spearmen by then.
You can still get caught out by mounted units if you didn't
build their counter, but the tech tree makes it unlikely you won't have it available.
Back to Bombers
Great War Bombers become available in the early Modern (Flight, middle path). Their primary counters are Triplanes, Anti-Aircraft Guns (AA), and Destroyers. The latter two come a half-era further in the late modern. The middle path gives
AA guns but Ballistics
requires Flight anyway. The bottom path gives
Destroyers but Combustion requires Railroads which requires Steam Power
and Dynamite, whereas Flight itself just requires Steam Power.
Triplanes are therefore the earliest counter coming with the very same tech that gives the bombers themselves. But like the Bombers they require Oil, which comes in the late Industrial on the top path (Biology).
This is entirely different to how the situation is handled in other parts of the tech tree, and pretty atypical for similar mechanics in other games as well.
In BNW we didn't care so much about this because it happened when we were typically "countering" with a surge in tech.
Acken's Version 4.1
I'm sure you're already thinking about ways you'd approach this (or how I've misinterpreted the situation), and I'm really curious what other ideas people have (I've got a few odd-ball ideas myself).
But at first glance I think the simplest way to smooth things out is leaving Triplanes where they are in Flight and moving Great War Bombers to Ballistics (requires Flight and Railroad) alongside AA guns.
P.S. Apologies for the double-post, but it didn't seem appropriate to edit into my previous post.
