About Cthulhu Mythos RPG -The Sleeping Girl of the Miasma Sea-

"Cthulhu Mythos RPG -The Sleeping Girl of the Miasma Sea-" is a retro styled horror RPG containing modern elements from the Cthulhu Mythos universe.

\


You, the protagonist, are 2nd year high school student.
It is summer and with your friends you have make your way to an abandoned mansion deep in the mountains to enjoy your youth and make long lasting memories.

With your companions by your side, overcome the terror awaiting you and unravel the secrets of the mansion.

\


Gender, name, parameters, skills... you can customize them all.

High parameters but lacking in skills.
Low parameters but an abundance of skills.
Create the protagonist to your liking and stand up against the terror.

\


Of the 5 companions you can only select 2 to explore with you.

The member you like, a member good at fighting, a member good at exploring.
Depending on who you choose, the experience you have may change drastically.

\


When the story proceeds you have the option to exit the mansion at any time.

If you run out of healing items or the enemies are just far too strong... you can give up, go home and attempt to explore the mansion from the beginning with your current level.
(You can do this even if you are defeated in battle = Game Over.)

Also, by unlocking certain achievements in game, the protagonist will gain a bonus to their parameters when you start a new game.

Take one step back and two steps forward. Giving up and starting over is an essential element to eventually discovering the truth...

Customize your character, pick your party, run into a mansion Sweet Home style and pray you don't get got by ghosts and other nasties. Learn the secrets of the manor. Visit a very dark annex. Explore the surroundings. Get chomped on by zombie dogs.

Survival horror/adventure/RPG mishmash. It's like Sweet Home or Laplace's Demon. Throws a whole lot of stuff at the wall and a bunch of it doesn't stick. There are entire skills that are effectively worthless, and scaling issues/exploits that render some characters much better than others. The stat system is pretty lopsided as well, such that stacking STR and SIZ seems to be pretty overpowered, given how limited magic and DEX weapons are. Throwing and ammo-based weapons are also not sustainable enough to be worth the inventory space. Putting that aside, the game just has a lot of charm to it. Exploring is fun, and there's a bunch of unique enemies and dialogue to poke at. There's also a fair amount of variety in how you can route the game, even if it ends up being pretty small once you know what to do. It feels like a game someone made because they had passion and fun ideas instead of one made to fit into a well-tread framework. Fun for several hours, with multiple endings and a New Game+ feature to carry over your levels and some completion bonuses.

Games like Undertale that remember what you did

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
