Software for Party PC

Hi all,

I was told to set up a "party PC" with games that are fun to play at parties. So far I´ve got:

-Ultrastar (Karaoke)

-Rocksmith (for Guitar)

-Emulators (for games)

What I would like to have is something like Rockband. Maybe where you can connect real instruments. Also any other suggestions what could be fun is highly appreciated.


(I´m that "I don´t do party"-kind of guy, so I have no Idea what I´m doing)
