Although I like WOF and 24, I feel like they could improve with more polish/better rules.

WOF's software was of course unfinished. The rounds were supposed to have variety and some of the wheel wedges were going to do stuff. Also more wizard modes and multiballs, among other things.

In my opinion, 24's modes lack variety and because they aren't timed, I don't feel like "every second counts". It'd be interesting if there was a mode where you're trying to disarm the nuclear football, and you're not only timed, but making the wrong shots could spell doom for the player.

There's also some other things. Like if you spell "CELL" via the inlanes and outlanes when a Cell Phone award is already lit, nothing happens and there's no benefit to the player. This is unlike Mystery in Metallica, where continuing to complete the inlanes/top lanes can make the Mystery award more valuable. The "Escape" lane doesn't do much. The CHLOE targets could do more. Have something for collecting enough red "weapon" shots. The list goes on.
