Yeah, I wouldn't plan on involving those types of characters I mentioned here; if I involved myself in the role-play that is. I can appreciate the desire for realism, and D&D isn't as off-the-scale as a lot of settings. I simply prefer more complex and metaphysical combat over more realistic, while my project's story itself is heavily rooted in reality in many ways. I'm the type of person who doesn't like escapism at all in terms of the narrative, but prefers the action to be more interesting than just fist fighting and people shooting guns; plus I like using abstract ideas. The elements in my work's actual plot that aren't entirely realistic are there to represent whatever philosophy or symbolism I'm trying to illustrate (even then my associates usually point out how believable even the supernatural elements of my work are), while characterization and such are entirely realistic.

Either way, I'll avoid being off the focus of the thread, since I was really only using it to emphasize how this is different to what I'm used to working with. It does sound like that Final Fantasy role-playing forum I was a part of did use the D&D system at the very least in terms of combat (mostly, dice were used to determine damage and whether actions were successful), though not in the character creation like you just described. Speaking of which, that's possibly the only immediate concern I can think of for how this system works; if our stats and aptitudes are more or less chosen for us on a dice roll, aren't you concerned it could result in an unbalanced match-up? Once again, I'm not proficient in how D&D works, so I might have missed something, but I did play one Might & Magic video game in my childhood that basically rolled up your stats with dice, so I think I know what you're implying with this.

Anyway, if I get some time I'll take a look at the guide you mentioned. While I don't usually work with conventional fantasy settings like D&D, when I do play them I usually lean towards playing wizards most of the time; that's the most likely class you should expect to see from me if I get involved. Other classes I use in fantasy settings don't really work in D&D so much. The chess player in me generally means I usually don't like combat systems with a heavy dependence on luck, but if I get time to look into the guide you've mentioned I might get back to you.
