Table Suggestions

My fiance and I are having a very low-key, non-traditional wedding. Our date is 9/13/24. We will have the ceremony and the receiption in the same tent, at the same tables. We have about 80 guests. We have two dilemmas... one, I want to make sure everyone can see our vows and two, one of our "fun" ideas is to have board games and cards available for guests to play. I was thinking a 60" round table, but that seems like it is huge to be playing a game or cards across. Also, what should I do about center pieces? Obviously not huge, so the guests can see and then should I have someone come collect them when they play games?
