First of all. This game,, even though it might become great, is not the best thing since slized bread. It's a crpg. The third iteration in its series. People that haven't been interested in crpgs before have absoluly no reason becoming interested in this one. Not when the title has the number "3" in it. Some people might pick it up based on hype in media but not the majority. The majority of players bying this game will be people that has either fond memories of earlier Baldur's Gate games, likes D&D/fantasy crpgs or liked Larians previous releases and hopes this will have the same quality.
Without proper data you can't know for sure you are right. Honestly I'm not sure you are
