the problem with playing W2 after having first played W3 is that you already know in the back of your head what's gonna happen.
====spoiler alert
your bro Roche wants to kill the rapey old king? yeah, sure, why not, might as well give him the pleasure coz Radovid's gonna off him anyways.
on a more problematic level, the entire Iorveth path turns pointless when you find out what happens via the comics. at least if you save Anais via Natalis, you can hold out hope that yeah, with the Ciri Empress ending Temeria will be a Toussaint-like protectorate with Anais as the titular head.
