I ruled out:
- AD&D (I don't like the restrictive class rules and I don't have the source books needed to open it up, plus it seems pretty old to me compared to D&D 3.5)
- D&D because the 4.0 rules seem pretty much like 20 years backwards and the 3.5 books aren't published any more (at least not at the moment and not in German), also I hate the (A)D&D rules for spellcasters - memorizing spells and then you can only cast 2-3 times or so a day, bah. I like Magic points or a system like Shadowrun uses where spells "damage" you and you have to resist with Willpower
- All the rule-heavy RPG's like Rolemaster and Rifts because that would be too much for the players
- (Old) Earthdawn because while I like the setting a lot it's pretty dice-heavy and confusing for beginners
- Warhammer, which is not light on rules, also I'm playing this in another group (Hooray for my Dwarven Rat Catcher

As I'm a Veteran of PnP RPG I'm not sure any more which systems appeal to beginners. The setting I can "easily" write myself, it's just the rule set I'm unsure about. Here are some I consider good:
- Savage Worlds: fast to learn and to play, but not so accurate. Uses D4 to D12 as stats for attributes and skills. (It's a generic RPG like GURPS, without a setting)
- Old World of Darkness: easy overview with only D10's, I never really liked the success counting when you got better and could use 10D10
- Call of Cthulhu: I like very gradiual progression of skills you get with the D% system, but is it confusing to beginners?
- Arcane Codex: character creation is a little tedious, but then it's always 2D10 + skill/attribute to roll, which is pretty easy in my book. Comes with a nice dark fantasy setting, too. That's a bonus

Maybe you have other ideas? My newbie days are long past but I remember it took me a while to get the AD&D rules with D20 and D% for thief skills - I never really understood the rules back then. I want my group to fully understand the rules early - because I intend to be a player again, one day

Long story short: Any suggestions for easy-to-learm rule sets which don't feel like they're too simplified?
