To me it seems that B/W and Stern have a different interpretation of what "easy to understand" is. Several B/W games give you a better direction what to shoot for. On IJ it also helped that artist Doug Watson layed out the inserts and was credited as a designer. Stern's (and this goes back to the DE and Sega days) idea of "easy to understand" seems to have been to give the player multiball as often as possible, with endless ball savers, thinking that that is what the player wants. Some players may want that, but I find it not very satisfying. Especially since it often is not clear how I started a multiball on a Stern game. To quote a designer from Pinball Magazine No. 2: "There is an old saying that still applies today: a game should be easy to understand, but difficult to master." That doesn't mean there should be a wizard mode that is impossible to get, as the 9 year old kid has no clue there is a wizard mode. But again, that's the difference in interpretation of what manufacturers think is "easy to understand". Which way is more fun is another discussion and also depend on personal taste.
