This might be a hot take but here we go.
Already bought it and played the early access for 8 hours.
To be completely honest, my hype for the game has deflated a lot after playing it. I'll still definitely play the full version, and I still expect it to be a good game, but back when I heard it was turn based I thought it was going to be divinity's gate 3 and it was my most anticipated game of the year, even in an insanely stacked year like this. Now I've played it, it feels a lot more like a turn based version of the Baldur's gate series (which is what it should be I suppose) than a divinity game.
To be clear: I don't find the DnD combat or leveling system anywhere near as exciting and rich as divinity. The DnD rules designed for group tabletop sessions don't translate as well into a videogame as a system designed with the intent of being a videogame from the getgo imo. Level ups come so slow and their gains are so modest, abilities with really average benefits still have a good chance to fail, and enhancements from finding new weapons and gear feel incremental.
This is all coming from a guy who never played DnD. My only experience with it is Baldur's Gate 1, Baldur's Gate 2 and Planescape Torment (all good games) along with every tv show that decided to do 1 episode where all the characters play a DnD game. The IT Crowd did it best btw.
So keep that in mind and if you like DnD mechanics you probably shouldn't be worried. But I would describe Divinity Original's Sin 2's battle system as one of the best in all of gaming, and Baldur's Gate 3, at least in the early stage, I would describe as alright. On the positive side, Larian seem to be doing a better job with characters, story and interesting dialogue choices so people looking forward to those aspects of the game should be excited. But for my part, when I thought this game would be stealth divinity 3 in a baldur's gate skinsuit I was over the moon and more hyped for it than all the other big games coming out this year. At this stage I still think it will be a good game, I don't expect to be replaying the game many times the way I do with divinity unless things really change with the battle system at higher levels or something.
