Quoted from lordloss:
No fancy rails, no mick on a stick, no invisiglass, no shaker, 7000.
I think that wouldn't be such a bad idea. Ok, you'd miss something with having no moving target (but a stationary one instead, in front of the right-entrace of the left ramp?), but that way a lot of people would still want the 'full version' and there's a possibility to buy a cheaper one with the same rules, but with a little bit different gameplay, but still the same rules.
I don't think having different rules for different versions is a good idea, but I do think Stern has a way to sell both more expensive and normal priced ones, because there's more difference than just art and invisiglass. I doubt though that from a software-point of view it's wise to make 2 different versions with 2 different rulesets.
Something in between, an interactive toy less, but still the same rules of the full version, could be a nice way to go and satisfy both markets?
