If you're into turn-based games, hold on to your butts, or wigs.
河洛群俠傳 (Ho Tu Lo Shu : The Books of Dragon)
This is in Chinese only, but wait! There is a fan translation patch, and there is one other weird thing where you have to change your time settings to Chinese,, but you can just reset when you turn off your computer. You wot m8? you might be thinking, but the game is worth every hassle to play it. I have beaten it three times since it released. The world is handcrafted, and full of things to do or find. Think of it as if a Chinese studio made Gothic, but made the game turn-based, party-based, and Wuxia related. Combat uses AP for movement and actions. You have a party of four. On second highest difficulty, you can add one more member, and on the highest difficulty, you can recruit people to have a 6 man party. You are free to customize your character, even if I advise a fairly focused build. One of the best games I have played in recent years. (Reviews are well over the limit, but it's mostly Chinese ones.)
TROUBLESHOOTER: Abandoned Children
This is a Korean tactical RPG. Again, you might be thinking: KOREAN!? Indeed, and it is great. While above game is my favorite RPG, this is my favorite TRPG. Customization options are insane. Combat encounters are fun. Some of them are super long, but you can turn off the game, and just pick up where you left. I play on the second hardest difficulty, and it is perfect for me. Very far into the game, you get access to customizing robots, and catching animals as party members. Amazing game, with great passion from the devs. Fans literally begged them for DLC. I have never seen a more humble development team.
The Dungeon Of Naheulbeuk: The Amulet Of Chaos
Your first thought might be that I'm crazy. You're recommending a game based on some French comedy radio show? Yes, yes I am. This has incredibly solid gameplay, and should be in the library of every fan of turn-based games. I would go so far as to say that this game has no right to be as good as it is.
King Arthur: Knight's Tale
Another tactical RPG, based on Arthurian mythology. This is a mix of XCOM and rpg. It can be really unforgiving, but is a lot of fun. It has a different take on the mythology, so it's up to you if you like that or not. Combat is solid, and you're free to recruit quite a few heroes. This is another top tier game that I recommend to turn-based fans.
Colony Ship: A Post-Earth Role Playing Game
This one is a crpg, and not a tactical one. The game is in Early Access, and I have had fun with it. I stopped playing, because I want to wait for the full release. Challenging, but fun. Allows you to solve quests in different ways, and non-combat stats matter. One of my most anticipated games of 2023 for me.
If you want more suggestions, I have quite a few more turn-based games, but I usually don't have the taste of general GAF. Not really that many AAA games bought by me anymore.
