Birthday party

To start, sorry if this isn't in the right category, but I wasn't sure I will be turning 17 and I wanted to have a small party with some girlfriends and maybe some guys. But the thing is I don't want anyone to be bored! So can anyone give me some cool and fun things to do at a party. I already have wii setup and music and speaker and I was thinking just pizza for food and snacks. But comment ideas!😊 greatly appreciate it.
