This is pretty typical pinside posting right here. You have a guy that actually gives the facts about a game, and everyone ignores those facts and then jumps to insults and learn how to play pinball.
Mark is right on all accounts. AC/DC is a totally average game with an interesting rule set that is destroyed by stupid cheap instant drains that are often times rewards for making shots. I see your "The bell is a risky shot" and my only reply is that a risky shot that is made should never reward you with instant drain. Additionally, as Mark has already stated, why would anyone find enjoyment in starting a mode that has the cannon shoot the TnT targets, which pop the ball instantly into the left outlane. Does this happen to you guys and you think "Gee, that was fun!" I dont even get control of the ball for this, it just happens due to bad software.
Maybe you guys should stop attacking a person for his honest feedback and instead come up with some sort of rational reasoning why instant drains for made shots is an ok thing. I like the game as well, but it is far from a top 10 game, and the only saving grace that AC/DC has is interesting software that allows you to constantly stack multiballs to make it ok to make shots that should otherwise be fun without the multiball requirement.
