if you're not an über-purist and/or you haven't had some good ol' deathmatchin' in awhile, you'll have a great time. the difference between QC and Q3:A/QL/etc. is that you pick a Champion character to play as, with unique health/armor/speed stats, as well as an ultimate ability. there's no restrictions on who can pick which champion (like Overwatch for example), and it's kind of like a "Super id Bros." as far as the characters go (still no Orbb though...). I played quite a bit of the game and while I tried some of the other champions, the default Ranger feels the most "right".
I've been paying for Spotify for 5 years, but I now only use it strictly for music. I find their UI for podcasts to be unintuitive and confusing, hoping they can update it soon.
