Sorry for the delayed answer. Wasn't able to get ahold of Vaiolis so we can go agree on something, but he's wandered off or something. Anyway...
Got another nitpick about your weapon lists. The prices feel arbitrary.
I guess prices are scaled to some combination of "realism" and "balance" but it looks like they're more just based on game-design traditions of pistols < shotguns < rifles < machine guns.
A new, semiauto, mid-caliber pistol is usually over $1000. A used shotgun or rifle (bolt or semiauto) can be $200.
Also, you should have some rating of reliability/endurance of the weapon - namely how likely it is to fail, or be damaged. Although, realistically, combat reliability (jamming and such) is far more dependent on the quality of the ammunition than the gun itself.
Once again, a decent point. Since this isn't as fundamental as the last one, not sure where it will go, but it'll probably be possible to buy used weapons somehow.
As for weapon reliability and jamming, it depends on how in-depth we want to go with the weapon thing. We'll have to see about that.
Question: What sort of country is this? We'll use different plans in a third-world country than in a developed one, strategies that would work in England won't work in an ocean-less country, et cetera.
We were thinking a US-esque sort o' deal, so far, but frankly that can probably be changed by player interest if enough people speak up. Another thing I need to discuss with Vaiolis.
From what I can tell, we are going to be demigods of war no matter what we use, as long as we are skilled in it. I'm sure dumping all of your points in throwing and getting a bunch of small stones will allow you to throw them at speeds comparable to guns.
Although one thing I would like to add is the ability to have one extra additional stat point at the sacrifice of another going down one point. Dammit, I want a large heavy guy that is very strong and pretty enduring. Just two points makes him unable to be a large heavy tough guy.
Taking a penalty in a third trait to assign one more to a different trait seems reasonable... Not sure if it'll go in, but it's not impossible.
Now, as for being demi-gods with any weapon you please... You're going to have a hard time killing without real weapons, be they guns or knives or artillery or suitcase nukes. In this case, if you decide to throw rocks as weapons, you'll probably die horribly if you attack someone who's actually armed, or get forced into hand to hand combat with someone who isn't armed. Rocks aren't any good for intimidating people, either.
