Hmmm. So far, the only thing I might be vaguely interested in is the Hedon sequel.

They also seem to be putting massive emphasis on gore in all of those games. Now don't get me wrong, I love gory games, but I quite dislike over the top nonsensical gore. It has to make sense to have any impact for me. If everything explodes like you just hit it with a rocket launcher even though it was only a single pistol shot, it loses all impact (the main reason I dislike Brutal Doom for example). It just seems like everyone is going with the "paint the room red", except you don't even have to use a weapon that would be capable of that. When every enemy is just a pressurized blood bag, waiting to be popped with anything, it becomes whatever...

Doom or Blood still did this the best by far. Hitting a cultist directly with a dynamite in Blood was so rewarding because not many other weapons would literally explode him into internal organs.

I never thought I'd say this, but there's way too many throwback boomer shooters in development at the moment. I'm watching the show right now and it's honestly hard for me to keep all of these blood-soaked shooters with crude graphics and pumping metal music straight.

So far, the only games that really stuck out to me are Hedon Bloodrite (which will definitely be coming to GOG), Core Decay, which is rumored to come to GOG, and Selaco, which will definitely not be coming to GOG because the GOG curators have been handling the game submission terribly and the dev basically gave up on trying to work with them, at least for the initial release.

I'll keep my eye on Kvlt.

The whole Realms Deep Live Stream was just a blast. As a fps fan I've tears of joy in my eyes with all the titles they've shown. Not all games shown where fps games only. Here are some of the games I wrote down because they looked absolutely dope and I hope they all appear here on GOG:

#09 GZDoom Game Developers Panel | Realms Deep 2021

The more or less complete (I think) list of every game featured during day 1 and 2 of this year's Realms Deep:
https://www.gog.com/forum/general/the_by_no_means_complete_list_of_indie_titles_of_the_summer_of_games_2021/post17

So, just skimmed through everything that was shown in the VOD and the list of things I could potentially be interested in is:

Already previously announced stuff:
Selaco
Graven

New Stuff:
Hedon 2
Amid Evil expansion (Black Labyrinth)
Ion Fury expansion (Aftershock)
Blood West
Dread Templar

Not much else really caught my eye in any way.

As someone who has a Blood Avatar you should check out Cultic.
