Current gen: the Dragon Age games and (more recent) the Divinity games are both very good series that (importantly) FEEL like oldschool turn-based RPGs, especially Divinity II. Before that, games like Neverwinter Nights. Before that, Baldur's Gate (available on ios!) is particularly good. Before that, there were a LOT of decent turn-based games but none really come to mind as being truly exceptional to me. Planescape: Torment is extremely well regarded but I only played that much later in life and found the emulator and 640x480 resolution to get in the way of the experience. You can also look into a variety of roguelikes like nethack and (older still) "text adventures" like Zork or even Adventure.
