I've played dos and dos2 and I liked them(well I enjoyed dos's combat system more than dos2 but I loved playing them both in general), I've never played any DnD games, should I buy bg3?
I haven't played DOS (though now I might). My understanding is that BG3 is more story and character focused.
And while they've done a surprisingly good job adapting D&D combat to video game format, it's definitely not perfect.
Yeah, almost all of it (level 14 or so). I felt the tone was super light-hearted, which was fine but I was concerned that BG3 might be similar. Fortunately, it's not it has a more appropriate tone.
To be fair though, we had our second child in September, so I'm just at the end of Act One (hoping to get some time to finish it over Christmas).
If you've played DoS2 you'll find yourself sometimes conflating the two quest lines sometimes :).
