I know, Tony Hawk 2 is addictive. I have been playing it ever since I got the demo in the Nov. PcGamer CD. So far my highest total score is about 597,000, and my highest combo w/o using the "bug" is 110,000. I can get a whole bunch using the bug. If you don't know about the bug yet, here ya go. At the beginning go to left and do wall slide on the wall but don't jump off. It should say a score at the bottom but won't disappear. Now do another wall slide w/o jumping off. It just keeps adding up as long as you don't "land" the combo. I have gotten up to something like 25,000 x 16 (over 400,000) from doing it.
Also have you guys found the secret area? The trigger for it is in the grass.
