It can be such a fun, unique experience. One time as I joke I started singing old rat-pack/crooner standards from the 50s, in the middle of a Halo match. When I stopped, my teammates actually begged me to continue saying it sounded really good and we were playing better while I sang. Literally nobody else has ever complimented me on my vocal talent, lol. Many hilarious situations arise that you could never get in other walks of life. But, yes, the obnoxious players ruin it (yet, it was much worse in Halo 2 IMO, it just didn't stop other people talking).
