Randal's Tuesday: "The game that no one asked for", "Best Prequel since Prometheus" says the trailer. Randal is back, this ime some years earlier, still in college. The game is already funded, the dev promised to try to come to GOG again. Stretchgoals for more content were not reached however, it's still possible to support it on another platform to make these possible.

Koa and the five pirates of Mara - sadly Steam only, but looks awesome.

The Adventures of Bryan Scott - great looking adventure with some of the voice actors from Broken Sword.

Twilight Oracle another adventure, looks as if it came straight out of an Amiga or early VGA machine. Has a nice 90s touch.

Official Trailer
Website

Anima: Song from the Abyss is an action role-playing game (ARPG) with hack and slash style elements in which players explore an interconnected world.

- The game is being developed by the creators of the role-playing saga Anima Beyond Fantasy and the videogames Anima: Gate of Memories and The Nameless Chronicles.
- Enjoy a memorable story whose course you can alter with each of your actions.
- Inspired by Nier Automata, Zelda, DMC and The Witcher.

Wishlist entry

It seems The Nameless Chronicles is a rather notorious case of the devs saying a GOG release 'depends on GOG' and the game then not appearing here even though the previous one did, so I suppose we shouldn't get our hopes up for a release here.

Profiler Files - New Orleans (38 days left, currently at 203 out of 25000 eurodollars)

Reveal Trailer
Website

As a young FBI agent freshly landed in the field, you will face all sorts of situations and encounter a variety of characters. Your choices, your intuition, and your deductions will dictate the course of the story.

How you interact with characters, the clues you find at crime scenes, and the psychological analysis you perform on suspects, victims, and other protagonists will determine the progression of the adventure, the success or failure of each investigation... and, of course, the outcome of the game and the central arc of Profiler Files - New Orleans.

- A hefty serving of branching narrative with multiple endings, within each episode and at the final resolution.
- A dash of point-and-click investigation.
- A large ladle of colorful characters and plenty of humor...
- ...which doesn't prevent serious, sometimes even grave, themes worthy of the best crime series.

Wishlist entry

Scribe (28 days left, currently at 6092 out of 50000 eurodollars)

Trailer
Website

"An action-, adventure-, and exploration-RPG created by a two-person team.

It features mechanics such as branched dialogues, quests, combat, crafting, stealth, archery, magic, and more, all presented in handmade pixel art graphics.

Players take on the role of a rogue Scribe on a quest to rediscover the true history of the Continent, a place where studying or even preserving pieces of true history results in the death penalty.

Our intention is to create a feature-rich RPG that combines everything we love from old point-and-click adventures, action games, and puzzle platformers of the late 80s, all of this without the constraints of old technology, and with a strong emphasis on exploration gameplay throughout. We want to push pixel art aesthetics to their limits and use present technology for gameplay features and content that would never have been possible in the early years of computer games."

Wishlist entry

Trailer

"Eden’s Guardian is a metroidvania game where the Player must fight against the corrupted Guardians on a pixel-art dark fantasy world.

In ancient times, the Guardians ruled the world, but as generations passed, their power waned. In a desperate attempt to maintain their dominance, they turned to a dark power that strengthened them but came at the cost of their sanity.

Take the place of an awakened Guardian from its long imprisonment to restore the world to its long banished shine.

Each Guardian has their own weapon. In our protagonist’s case, she’ll be equipped with her sword, which allows her to teleport to any place where she throws it.

With this ability, she’ll be able to surprise enemies and hurt them where they expect less, and reach places that would otherwise be inaccessible."
