Company Christmas Party

I work at a plumbing company in Kansas. For the last 3 years we have had some very good parties. I try to incorporate teamwork and unity into the party plans. We have appoximately 60 - 70 attendees. I need some ideas such as group games or party ideas where both men and women can play.

Last year we had a casino night after our dinner, the year prior we loaded everyone on a bus and went to the mall, gave them company money, did not let them go home with any money, they could only spend it on themselves any money they had left over they had to give back. We came back from the mall and everyone had to show everyone else what they bought. Everyone had a great time.

I am having a very rough time trying to think of something. Any ideas please.
