Any game that doesn't have a skill shot is missing out on an opportunity.
The plunger is a unique "feel" aspect of pinball, and should be used to the fullest.
Half of the games in my collection are missing one. (not missing a plunger, LOL, a skill shot.)
If there were 2.0 releases for all the machines in my collection, the skill shot issue would be remedied simply by disallowing a 1-2-3 lane change until the first 1-2-3 lane switch is registered, at that point, allow for it, when the pops take over and try to help you score another lane.
