there are definitely fewer games.
for me personally, i take one day to enjoy everything at Expo. This is a show where a lot of "new" game announcements are made. Rumor is that JJP #4 will be unveiled at this years expo. Also, if you have a car then it is worth the drive out to Huntley for the Pinball Life event. If you don't have a car, just find someone that is going and hitch a ride.
