Yesterday I mentioned about snowboarding games, which boils down to: arcade-trick style (SSX, Amped), tech style (Shaun White [regular - not Road Trip], Shaun Palmer, 1080) and back country style (Stoked).
I should elaborate it further:
Those arcade-trick style like SSX tends to have absurd tricks (to the point of physically impossible) - little more than a button-masher on a snowboard. Graphics and plot also tends to be a bit cartoonish.
Tech is also about mad tricks but more realistic. Those are the frestyler in the snow park.
Back country style is about the freedom. The freeride down the mountain is what it is about.
So it is essentially park vs freeride.
