I personally would like to see the new style system (independent of weapons) be expanded upon further. Any variety to melee combat, almost always a boring but staple option in a roguelike, is a good thing. When combat insights and fighting techniques (or even just practice techniques) were discussed, the idea did hook into my mind, but I didn’t catch this thread until just now.
This is probably a distant idea but shouldn’t it be possible for your character to assemble his own unique style? Over time, learning to fight something not entirely human, with little prior experience (for most people) in combat, wouldn’t most people develop their own method of combat? Unfortunately, the way for the game to develop a style based around your actions as a player would probably be difficult to code in, and involve a lot of analysis over time. Maybe, however, between melee (or weapon-specific skills) skill of 6 - 10, assuming the previously discussed exp curves and caps, your character should have breakthroughs on methods that work well.
The style, generated upon your character’s fighting style until then, might then be only applicable to either a favored weapon that you use almost exclusively, or a group of weapons within the skill that’s in those levels if you switch it up. It probably wouldn’t be as sophisticated or effective as martial arts styles, and I hope more are introduced that primarily affect weapons, but it would be, do a degree, tailored towards your own style as a player.
And of course, I think the practice thing is great. There are a few skills that are hell to train to any decent level without hiding in your cave for almost a month with books stacked to to the ceiling. Computers and Electronics I am looking at you. First Aid I wish had books that took it past level 3, but it’s not terribly important that it does. Mechanics I can train to 10 in a day with a hacksaw and a wrench and a few dead cars, and that’s kind of a problem. I can get it to 40 and well beyond just making my own vehicle.
