^the guy above me makes a valid point- most parks in europe tend to be set out in a big area with the features all side by side, whereas parks in north america tend to be one feature after another down a longer run. it's just a different way of doing it- EU: lots of short laps with fewer hits- US/CAN: longer laps with more hits.
however, i think it's no longer accurate to say that european parks are way behind those across the pond. in the last couple of years not only have parks been springing up all over the place in europe, but they have been getting really good also, to pretty much the same level now i think.
here's a couple of examples of the better parks about europe:
those are just a few that i found quickly. there are so many good parks all over europe now!
