Fall of the Samurai Enhanced

FotS Enhanced seeks to improve the gameplay without resorting to drastic changes that change the feel of FotS. It's a compilation of the mods I've done so far, but also includes some other tweaks I haven't released yet, either because they were too small in scope or very similar mods were already on the Workshop. You can click on the submods to see the changes in better detail. All changes are represented in the in-game tooltips (not in the encyclopedia though, that's not moddable through Workshop).

This mod is (currently) lighter than S2E, since vanilla FotS doesn't have many areas that can be improved with small tweaks. The exception is the defence slot feature, which mods the startpos file, you can find FotSE without that here:
FotsE without defence slots

Highlights:

AI: The core of this mod. Finally, HedgeKnight's Ultimate AI is updated for FotS, for an AI that better manages its recruitment, research, building orders and invasions while cheating less. AI recruitment is significantly improved without taking away the diversity, expect more artillery and rifle units. Also includes Yarki's Reduced Cheating.

Autoresolve: Improved calculation of army strengths for less lop-sided results, with the goal of providing a reliable and reasonable autocalculation, so that you don't have to play every little skirmish by yourself. Rifle infantry advantage over traditional units is reduced to sane levels, you can actually take losses now. On the other hand, naval advantage is more prominent, winning fleets will take less damage if they have a significant advantage. AI autoresolver bonuses in hard difficulty are removed, those in very hard are reduced to hard levels. Winning armies have a better chance to capture artillery units.

Battles: All unit movement is slowed by %15, melee engagements also last around ~15% longer. Fatigue decreases at a slightly lower rate. General morale radius is increased. The weather has more effect on accuracy and reload rate. Includes Freelancerx's Better Ambush Deployment, rifle units can start firing as soon as the battle begins.

Buildings: Accuracy bonuses provided by Riflemaker and Firing Range are lowered by 5 to prevent easy recruitment of supersoldiers. The AI is now aware of the synergy between these buildings and artillery unit recruitment. Both Castle and City chains gain +1 of their respective garrison units.
The artillery chain provides the following units: 1 Wooden cannon at Tier 1, 1 Parrot Gun at T2, 2 Parrots at T3, 2 Parrots and 1 Gatling at T4.

Bombardment Nerf & Tweaks: Bombardment radius is reduced and successful bombardments require more ships. Small boats cannot bombard anymore.

Campaign: Increased the zone of control for armies and navies for better strategic control of the map. Minimum unit strength requirement is also increased, making it easier to destroy units. High & very high tax levels are slightly less damaging to town growth. Sons are guaranteed to reach adulthood (and become generals) earlier. Income bonus for minors reduced.

Defence Buildings : Each province now has a dedicated slot for defences and starts with Matchlock Towers. Defences are less costly to build and research, and stronger in battles.

Units: Matchlock Kachi does not require technology, but starts weaker gains XP with Shih. Artillery units are slightly less accurate.

Fixes: Suppression fire reduces the target's movement speed.

Compatibility:
Dedicated defence slots sadly hurts compatibility, do not use it with any mods that edit startpos, the modders should state if their mods edit that. This includes many large overhauls (Darth, Radious), any mods that make changes to map (adding/changing regions e.g. Extended Map, new clans etc.), and turn-per-year mods. Blame CA.
Yogi's artillery & uniform mods should be compatible.

Recommended mods:

If you enjoy this mod, rate it! Rating brings more subscribers and (hopefully) more feedback, which leads to better mods. Check my workshop for similar mods that enhance the vanilla game.

Possible additions:
Further AI tweaks (may integrate reliability tweaks)
Ability tweaks (square formation for elite inf., pikewall for yari kachi etc.)
Bombardment rebalance

Credits & Thanks:
I learned modding by studying older mods on Total War Center, TROM3 and S2TR were particularly informative and inspiring. If you're interested in mods with more profound changes, be sure to check them.

Possible Issues:
The "arrows sounding like muskets/cannons" issue is a general problem with modding Shogun 2, i.e. it is not related to this mod and the CA should've fixed it a long, long time ago. You can get a community fix here
