Alright, I gotcha. I figured it was more simple than I [over]thought.
And thats one of the big things I love about this system: the fact that skills are much easier to advance when they are lower, and recieve larger advancements. Then, as the skill grows, so does the value one must subtract from the roll, consequently leading to lower totals and eventually: no advancement. And then, one must attain ADV bonuses to actually achieve a high enough total to get onto the chart.
This makes perfect sense in relation to real life, as one gains in skill (talent, etc.) much faster in the early stages of, say, mastering a craft. The closer to "master" that they become, the less there is to learn, and the harder it is to learn more.
The realism of Arduin's mechanics are what attracted me to role playing (from the [in]compleat Arduin, no less). I had originally tried D&D 3.5 some years ago and quickly lost interest. My dad had used to play a combination of THACO and the old Arduin supplements (just the first 3) mixed with touches of other systems like the armor rating from Palladuim. He stopped role playing [or so he thinks] right around when the Compleat Arduin came out, and never saw the awesome BF system. However, a group of his friends that loved his sessions so much did pursue it. 10 years later, now that I can hold interest on something for more than 20 minutes, those old friends of my dad's got me in on a session, and I was hooked. I never even got to finish a campaign, nor even experience the death of one of my characters, playing maybe a dozen sessions total before it all fell out.
Now addicted and wanting more, I talked a handful of my friends into trying Arduin, in which I was GM (I wanted to really play, but at least I was around it). Surprisingly, for 6 "noobs" who had never played an RPG and one GM who had very little practice himself... it went good.
Soon, I discovered Arduin Eternal. I instantly got the book and slowly chewed through it. Going through all the stages of course, from: im totally lost, to: okay, I still dont get it but this seems really cool, to: ahhhh that makes sense now... I tried to run a game with the new system but my players lost interest at this time, partially because I was still stumbling with them through a 3 hour character creation process, and partially the location we had available to play (very cold!).
After that I had no more Arduin dealings for about a year, then, my dad's friend, the one who turned me onto Arduin 2, calls me up with question on Arduin 3... He had had the book as a supplement for Arduin 2, but now wanted to learn the new system- he wanted more structure, he said.
It was awesome watching him go through the same stages I did, growing very excited at how the system ties together in complete structure, leaving nothing out; and is so very Arduin in it's mechanics, however different from Arduin 2. "Compleat" can now be spelled correctly!
Anyway thats where I am now, waiting to finally play again (I don't want to GM quite yet); I have a Hobbit thief rolled up and ready!
