These are the ones that come to mind. If they are on Steam, I go by that release date.
Everquest 2 Ballads of Zimara - I have been playing EQ2 on and off since release. My friends and I have played together since Everquest. Running the guild is fun and I enjoy their company immensely. The expansion itself has been pretty fun. A decent amount of content for like the five people who worked on it. Better than the last expansion.
Dragon Quest Treasures - This may be my favourite game this year. Likeable characters, fun story, great enviornments, awesome dragon quest music, fitting sounds, varied zones, great exploration, and many of the treasures you find were from previous games. I am super bummed it wasn't received well which means no sequel. I am a huge Dragon Quest fan and have been playing since 1. This game was so much fun.
Elder Scrolls Online Necrom - For me, this game is all about the story, lore, and exploration. Necrom met all those requirements. Really captured the essence of everything Hermaeus Mora. Ended on a shitty cliffhanger which was really weird for ESO. But it sounds like they are going to take the story to Tamriel proper for the next one.
Soulash 2 (early access) - Not sure if early access counts. If not, my apologies. Soulash 2 is still rough around the edges. I won't go to into the game overmuch, but I have clocked in a lot of hours considering it was a recent release. Good exploration, a lot of skills to work on, and is quite replayable.
Moonring - I don't understand why this didn't get more traction here. Maybe the neon colours. If you haven't played it and like Ultima and turn base combat, try it. It's free.
Lunacid - King's Field like game. Very good exploration, challenging at times, secrets, interesting weapons to play around with, great music and feel to the world. As a warning, the trannie who made the game added pronouns on the 1.0 release (the game was in early access and didnt have them) and also taunted people on twitter about it.
Etrian Odyssey HD - This is an older game that was given a fresh coat of paint as an HD remaster. Some solid quality of life improvements. It's a dungeon crawler with a cartography system. Very enjoyable for what it is. Very much an anime aesthetic, if you are senstive about that type of thing.
Colony Ship - I am only 20 hours in so far as I just started a few days ago. It has been amazing. Very easy game to immerse yourself in which is exactly what I have been looking for. Going on a bit of a binge, which is something I don't often do anymore. Looking forward to where my choices take me.
