I can't speak to how BG3 compares to PoE, having played neither, but the older Baldur's Gate games routinely go on sale for a couple dollars on GoG, and the Divinity games are also similar and old enough to see deep sales. If you want to try out the genre, there are plenty of options to do so without dropping $70.

In any of those cases, if you're struggling with all of the skills/abilities, you can always look up build guides to help you get a grasp on them. You don't necessarily have to follow them ton the letter if you don't want to, but they will at least tell you what works and help give you the foundation to be able to figure out everything else.
