Don't think I've played atlantis. My favourite EMs are probably abra cadabra and jacks open (I played this the most growing up as a family friend had one).
At the moment I've got a ripley's believe it or not, space jam, comet and whirlwind. I'm looking at moving the comet to my dad's place so I can find room to add something else though.
It is pretty crazy how much is going on with a pinball machine that most people never realise. Most people who come to my place have never actually seen inside a pin, I'm not sure what they expect them to look like but they always seem so surprised by how much wiring and how many different things are going on. Crazy how much depth most modern rulesets have that a lot of players never actually understand or realise exist.
