  • I’m a noob, but often what drives up lens cost is the complexity associated with making the image better over the whole field of view. Lenses have various inherent errors (called aberrations) that are corrected by a combination of complex surface profiles on individual lens elements and stacking multiple individual lens elements to cancel each other’s errors out. A scope likely only needs good correction near the center, where the user will be looking most of the time, while a camera lens needs good correction everywhere so the whole photo looks good when you view it later. Wider field of view makes good correction much more complicated and expensive very fast.

    I like the Avatar Legends RPG, and the lore included is great. But I hate how spread out the rules are and how much hunting around I find myself doing. They probably could have put all the rules in a concise, 20-30 pages or less. Then the other hundred or so after that could have the lore.

    It’s PbtA. Very easy to GM and to play. But it’s still hard to convince people to try it, even people who like ATLA, because the rule book looks so long.
