I just saw this new dark Transylvanian vampire HoMM like game called Immortal Realms: Vampire Wars
for PC, PS4, Xbox, & Switch in one of my recent PC Gamer mags. In their preview they talked about it's closeness in gameplay to Heroes of Might & Magic and gothic art style to Disciples. I also notice it has a Eador & AoW-Planetfall like territory/province system, a research system (called legacy), and it looks like most of the game's mechanics (empire, heroes, spells etc) revolve around an interesting card deck system and all the cards have these cool animations. Looks like there's no gorgeous HoMM style city screen where you build buildings but in the main map view you can develop provinces with some interesting building upgrades.
I just checked and the game got released a couple of weeks ago on Steam & GoG. Metacritic score looks pretty good at 71%, steam score is not as good although most of the negative reviews point to bugs and AI issues that will hopefully be sorted in patches (Kalypso shouldn't pull the plug on them as there's console releases coming so they'll wanna iron out all the bugs). No multiplayer which doesn't bother me but I know it might bother others so thought I'd mention it.
Here's an old preview video of it.. I love that foggy night map shown around the 2min mark. I remember preview videos of HoMM5 had undead foggy dark night time maps that excited me but the final game just had the usual not so foggy day time or dusk undead maps. I can also see myself spending ages just gawking at all the card animations instead of playing the game haha.
A much more recent video where a guy plays the first campaign mission for half an hour.
Another new video where a guy plays a skirmish game against what appears to be a lot of AI factions which is cool.
