About EOS-503

EOS-503 is a free, publicly available roleplaying game designed to help teacher education programs compare their students’ application of instructional practices, technology integration skills, and visionary leadership with traditional evaluation measures like exams and portfolios.

Developed by and for teachers, all interactions between the player and non-player characters (NPCs) are bona fide representations of the thinking and action employed by real-world educators in real-world teaching and learning environments. This approach is particularly effective for humanities content—philosophy, history, education—where designers can help the player “think like a philosopher,” “think like a historian,” or “think like a teacher.”

Players are tasked with persuading the game’s NPCs to change their points of view, first by identifying specific cognitive theories at the heart of an NPC’s worldview, then by deciding which dialogue options have the highest probability of successfully influencing a given NPC’s thinking. Unlike multiple-choice tests or essays, EOS-503 leverages responsive roleplaying elements and branching plotlines to bring learning theory to life—every conversation incorporates multiple philosophies to be explored, and every player choice branches into dozens of potential story outcomes.

EXPLORE


Traverse the four factions of EOS-503. The Hub, People's Republic, City of Seekers, and Worker's Hold all share a home on EOS, but you won't find many similarities beyond that. From agricultural fields, to art festivals, to brutalist cities torn by political unrest, there's plenty of areas to explore. During your adventure, keep an eye out for collectibles; you may discover more about the world around you, and learning theory, through each one!

SOLVE


As EOS-503’s newest DATA Agent, you will solve social conundrums by applying contemporary theories of thinking and learning. The choices you make ripple through your conversation partners—different arguments lead to dozens of different story outcomes, increasing replayability and allowing you to reflect on the effectiveness of your recommendations for different people with different worldviews.

Although data collection is inactive by default, teacher preparation programs can contact the developers to track individual student progress via anonymized User ID Numbers. Dialogue choices, lag time, and more can be paired with portfolio and other assessment data to evaluate learner growth over time!

CUSTOMIZE


Create your own character with hundreds of cosmetic options. There are no gender-locked options, so your DATA Agent can wear the clothes and accessories you love most, and rock any hairstyle! Change up your look at any time, right from the pause menu. Customization options also extend to your living space- interact with your environment to swap out furniture colors and styles to make your space your own.

EOS-503 is a pretty neat game about education theory and using diplomacy to improve the lives of the inhabitants, I must say, I think I have a better understanding on resolving conflicts and such topics. It's a neat game overall.

Hey screen cuts off in ultrawide, even when using full screen. Cannot adjust windowed either

I spent about 2 hours playing this game. Overall it was a fun enough game. A shame it hasn't gotten much recognition since its release in 23. I would definitely recommend it to others.

Can't say I enjoyed the time I spent in this game. The conversational... elements... really... bothered... me. I found myself... more fighting my annoyance... at how the conversations... were... presented... than enjoying the thought necessary... to... resolve... the situations.

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.

Games like Slay the Spire that keep the branching climb

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.

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

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.
