Finished Witcher 2 on Roche path - bro ending & Roche path - waifu ending. It seems a couple of new quests were added courtesy of enhanced edition, so spending those hours downloading 10 gigs was worth it.
Now to play Iorveth path.
But as of now I'm not sure what save I'll import into Witcher 3. Roche bro ending leaves a very bad aftertaste, hopefully Iorveth path will be more uplifting.
