OK, I have a fair amount of play time under my belt, enough to have earned over 400 EP's. I joined a game in progress so started at 1300 EP's and just getting into the Pistoleer profession after starting/finishing the Noble "profession".
As for the question about how do we make money. We have a haggler in the party, so we make good money off of equipment. I just got a full set of plate mail the session before last, due to how much we made off of equipment. We are fighting stuff with average quality weapons and even a few full suits of chain mail. I would say for every 100 gold we have been "earning" so far we have made 300 from selling equipment, books, etc... With a haggler at 50% we have been doing well on prices.
Is the game deadly? Yes, but still much like D&D is. Once you get good gear and your weapon skills start getting to 40% and higher. Like my PC is a dwarf, and his toughness just advanced to 51%, so he now, with his armor, negates the first 10 points of damage . Since all damage is on a d10, I now only take damage from only their strength bonus, and only when the damage dice is high enough.
Still, it can be deadly, like tonight I still got hit often enough and well enough to take 8 wounds, with only 3 PC's fighting 12 beastmen and two of their leader types, so almost 5 opponents each. Could we have died? Yes, but with our toughness scores, and armor, reducing the damage, even though we got hit often enough we shrugged most of the damage off, allowing us to kick butt.
So this game allows for you to start in the dirt, literally, but with luck, you can survive long enough to eventually get a lot of gold (my character has almost 2000 gold coin worth of gear and coins now) and be well equipped and skilled enough to be pretty darn tough, but still know death is very possible despite being as tough as you are.
In other words it feels very realistic, you feel like a soldier who stays alive due to his wits, skill, and luck. A feeling you don't always keep in a game like D&D.
So even though my character is pretty darn tough, with great armor, and nice weapons, he could still die, just now the GM likely needs to get in 4 to 5 hits with max damage in quick succession. Not very likely, but still possible, and you know it. So the feeling of risking your life is still there.
Plus this is without the GM throwing nastier creatures at us. Like he hasn't thrown Trolls at us, and they are pretty nasty. Then there are Chaos demons, which are worse. Far worse.
One thing I am really liking about this particular game is I feel like we are playing out those cool scenes from movies. Our superior equipment, training, skill, and teamwork, with a decent dose of luck, allows us to kick butt, take names, and still take a beating and still come close to losing a companion or three. Fortunately our group has managed to stay alive, and we now have a healer!
So yes, you can make WH as gritty a struggle in the mud you want it to be, but you can also make it anything above that, and you'll have fun.
Just realize that WH is a percentile system, where rolling low is good, and all damage is based around the D10, but is as gritty as you can imagine, but you can also drag yourself out fo the mud and become a respectable hero.
