Is the system fairly easy to learn? I have the rules. I just haven't looked at them, other than to try to create a character for Numenera.
Yeah, I found it easy, though I disliked how the Numenera book was arranged. Essentially anything you want to try, throw a d20. The difficulty is based on the level of the creature/NPC/object/item/etc (everything has a level). If you're trained or inhibited somehow, the difficulty of the check goes up or down by preset amount.
And that's mostly it. The same rules apply to combat, initiative, items, skills, interpersonal checks, all of it. There's a bunch of little exceptions that the DM needs to know about, but that's the gist of the game.
