Do I need shower games?

I'm having a very casual cookout baby shower. It's coed, kid friendly and at a park. Do I really need shower games? There's going to be a diaper drawing and corn hole but I think with the amount of people showing up (75-100) that it will be top much. My shower is only 3 hours long and in between socializing, eating and presents plus corn hole and kids that there won't be time left from games. What do y'all think? Is it rude or odd not to play games given the type of shower I'm having ?
