Overall, the EA game-space is interestingly designed, and the story elements are a reasonably complex weave that looks like it will produce an interesting game, provided you can overlook the weakness of some of the 5e rules and combat ( personal opinion, I can't judge if you would share it ).
Yes, the availability of mods is what I am now heavily counting on to make the game palatable for me.
The one area of the game that I am very okay with is BG3's deviations from D&D rules. I am 110% with Vincke when he says sometimes you need to deviate from the PnP rules to make the game be interesting and fun to play as a video game. Personally I'd be happy if they deviate from most D&D rules and mechanics, because I don't care for D&D that much anymore. My interest in BG3 is primarily as a Forgotten Realms game and not as a D&D game.
