Here’s a fun thing you can do: just stop thinking about stats and make a character you’d like to bang, then just ooga booga it.
Baldur’s Gate 3 may be very daunting at first, even with its genius tooltip system, so I just went straight into it with a Dragonborn barbarian with no real thought put into it other than “he’s hot and totes my new fursona”. You’d be surprised at how far you get and how much you pick up naturally over the next 80 hours of gameplay.
That being said, it’s still not for everyone, as much as it tries to be, and if even Overwatch is too complex for you already, it might just be that the evolving game design in the industry is becoming more misaligned with your tastes, and that gamers are becoming more and more serious about the video games they play.
