I’m hosting my own shower.. would it be weird if I didn’t give prizes for the games?

I’m paying for my own babyshower. And it’s to the point where I’m using more money to host this shower than what it would be if I just bought everything. And honestly, we really have everything we need. All the big items. And most of all the smaller items. But I’m so far into the babyshower that I would feel stupid canceling. Venue is paid for, all the decorations are bought.. food is all planned out. But I asked my SIL to host the games.. and she asked me if I had the prizes bought. It got me thinking.. now I’m gonna have to put even more money into all the prizes now. The amount of money I put into this shower is just through the roof.
