As for the Eurogames... I find them a bit hard to stomach these days. I shot myself in the foot by introducing friends to Ticket To Ride and Carcassonne, thinking we'd quickly move onto geekier stuff like Talisman. My plan was to gently win them over to the very idea of playing boardgames. Thing is, they just became utterly obsessed with those two, and I got completely sick of them. One night we played a great game of Cosmic Encounter. Lots of trash-talking and silly banter, lots of fun. Then we played a game of Ticket To Ride: Europe. 45 minutes of the three of us gazing resolutely and silently at the board. That's the difference between the two types for me.
See, your mistake there was game order*. You start with a game of, say, Catan, as you start drinking. Rivalry, arguments, frustration... and then someone wins. And now, everyone slightly pissed, you bring out Roborally (or equivalent game - I've not tried Dungeonquest yet, but it sounds similarly suitable) and giggle like idiots as people drive themselves in circles, off the board, into traps...
Incidentally, anyone who hasn't already must play Roborally. It really is fantastic.
*though I will admit that I've gotten tired of some of my friends' obsession with Catan/Carcassonne. Turns out there can be too much of a good thing.
