Quoted from alveolus:As in, only by a technical definition would one conclude Funhouse is not a system 11 game. For the player who is not opening the backbox, they see an alphanumeric display, system 11 siderails, a non-clearcoated playfield, and a game that plays much more like Whirlwind than TAF.
Funny that the one that I consider the most quintessentially System 11 (but isn't) is Party Zone, followed by BOP and then FH.
But I think there is some form of logic to it. I find that System 11 games have a particular feel to them. I attribute it to the fact that there's less crap between the flipper buttons and the flipper coils.
I think that one reason people often mistake the early WPC games as System 11 is because these games were pre-fliptronics and (if you discount the changes inside the backbox), the electronics is pretty much identical. So they had the same general look and nearly identical feel to the games before.
Out of all the pre-fliptronics WPC games, T2 seems to be the only one that doesn't look or feel like a System 11 to me.
My favorite S11 game? Whirlwind.
