IS truth that they confirmed that wish will be in the game? If yes, it should be a EPIC quest to get wish and should be like one wish per campaign.
About dos2, i din't liked the eqquipment fever, the cooldowns, archers limited to 13m, necromancers to one summon, lets hope that Larian makes BG3 more old school like and less modern like. DOS2 is a good game, is just not for me who can't enjoy this modern mechanics and who has my immersion broken by this mechanics...
