For me personally many of those high fantasy polished D&D based games have become quite boring. I mean they objectively are of high quality! But I couldn't e.g. manage to finish both Pillars of Eternity games because they somehow just became a chore to play further. The writing was great, the visuals were great, but something was still lacking. Achievements and collectables and similar 4th-wall-breaking elements were a turn-off for me, and the D&D ruleset again and again...

By contrast Jeff's Avernum series was such a breath of fresh air. Really interesting world, great writing, no D&D. Those were really great. I wouldn't mind better graphics, but that's a minor point for me.
