Nice to see some nods for Tee'd Off. Especially with the outrage that its inclusion brought!
For me, it's Attack From Mars. Prior to TPA, I'd never heard of the game so wasn't familiar with it at all. Knew nothing about it. Fired it up, didn't expect much at all. Now it's easily my most-played table.
Not sure if serious.....
I had somehow never heard of Black Rose before TPA, so that sort of thing is quite possible.
I also hadn't heard of Class of 1812, El Dorado, Genie, Goin Nuts, or most EMs, though those are all a bit more understandable.
I'm going to say Tee'd Off. Post-Black Hole gottliebs are largely really terrible, but that table manages to have an astoundingly complex ruleset with fun shots, a pretty unconventional layout and a nice retro art look.
Black Rose!
