I hate what the gaming landscape has become.
Micro transactions, seasons passes, small dlc that are often poor money for value, in some cases in the past as well we’ve seen endings sealed behind dlc or things that clearly should have been part of the game but cut out just to make people buy them as dlc.
My most recent purchase of an expansion that really sticks out is probably Xenoblade 3 where you get a whole new story arc and it’s pretty big in terms of expansions.
Why does it stick out? Because it’s very well done and extremely good value for money.
I wouldn’t buy buy DD2 if you want more BG3.
You’re better off playing BG1 or 2 if you want more though they might be quite dated for you.
DD is more open world action rpg, I’m not sure about the story of this one but it’s nowhere near BG3 apart from being fantasy.
