Sill playing Aurora. Missle combat is very different and it took a while to learn. I'm hitting my stride now I feel.
Also in the middle of Citizen Sleeper. An RPG where you're playing a transhuman cyborg traped on a space station. It's been interesting. I would compare it to Disco Elysium. That title obviously had a better budget but Sleeper holds up well.
Just finished Observer: System Redux. It's a cyberpunk/horror game made by a Polish studio. They did a good job using the medium to create a sense of dread and foreboding.
Also playing Aurora, the free 4x most people compare to Dwarf Fortress. A new release came out a few weeks ago and it's fun to learn the new mechanics.
Mostly in combat mechanics and story progression. You declare attacks and draw modifiers from a deck to see how you fair. Individual pilots and ships have different abilities that can synergize well. You don't need to loose abilities to refresh but you can to mitigate damage. The missions that are selected based upon the choices of the group. Unlike Gloohaven you don't destroy cards or stickers so it's easy to replay. There is also an exploration game baked in which is a welcome break from combat. The worst thing is the lack of enemy variation. The writing isn't the best either. I picked it up waiting for FrostHaven and I'm not disappointed but GloomHaven is definitely the better game.
Cyberpunk 2077 with a bunch of mods. The Enemies of Night City mod is actually making the game interesting and somewhat of a challenge.
My group almost finished Act 1 of Stars of Akarios it's a GloomHaven-esque game set in space. You play a group of fighter pilots and engage with other craft. There is a very neat exploration mechanic too which I really enjoy. There are some teething issues but that will hopefully be corrected in the next release.
If you're looking for something complex the various COIN games by GMT all have a solo mode. The way the factions interact is usually interesting and you can familiarize yourself with some history along the way.
Ico is such a wonderful game. I wish I could play it again for the first time.
