World of Warcraft, Final Fantasy and Dragon Blood are MMORPGs which means learning a lot of mechanics and timings which, if you are not too familar with combat in RPGs, could be a hassle.
Bladurs Gate 3 is only in early access so a lot will change and its currently set at a “Classic” difficulty which is tuned for fans of the genre and people already familar with the combat.
I would recommend starting with Dragon Age: Inquistion for a number of reasons. I really enjoyed it, its got a good story with interesting characters and still looks great. It also offers difficulty settings that can be changed at any time, so you can start on Casual which gives good bonuses, limits the AI and stops friendly fire and if you are finding it too easy pop it up in difficulty and back down for hard fight.
The other big reason is that you can get Dragon Age on EA play for €3.99 a month and it gives you access to other games in the Dragon Age series, or even on Xbox Game Pass which has EA play included for €10 a month for even more games like the single player Final Fantasy and Pillars of Eternity games.
