101, 301, 501, 1001, etc., forces throwers to be good at math. Throwers can get by with someone calling the numbers for them but that will only get them so far. Cricket also forces players to do the math.
There are plenty more games than 01 and Cricket. Killer is one.
Shanghai is another one and it makes Baseball look amateur. In addition to potentially using all of the numbers, it has the additional challenge of not starting on 1 each time like baseball. Throwers need to be able to start from anywhere.
As for the physical darts, there's something to be said for each thrower having their own darts: weight, balance, diameter (tungsten percent), shaft length, and other things such as hammer head points. Some throwers who are good enough to throw all three darts into a triple or a double bullseye appreciate spinner shafts.
There's a reason thousand of people go nuts watching English dart tournaments but few watch American darts.
With a semi circular/equidistant heel line, you could certainly hit a target as small as a double bullseye on a bristle board with 3 wooden darts, but not easily. Older brass darts seemed heavier w/ barrels not much smaller than the wooden darts.
