I've only owned 4 real pins (Lost World, Johnny Mnemonic, Avatar and AC/DC) I have been to PAPA and the Ohio Pinball Show last year... so... I've played quite a few pins....I'd say that AC/DC definitely seems like one of the fastest I've personally played. I think that everything I play in limited amounts seems fast because you are un-firmiliar with the machine, but ACDC always feels fast. My Avatar seems like slow motion compared to ACDC. Since having ACDC my Avatar high score went from like 23 million up to 38 million, but that game is IMO a lot harder to score high in than ACDC. ACDC you can have 10 million in like a minute and with Avatar I'll go 5 games in a row and not hit 10 million.
