Daniel Janik has built a game that runs entirely in SQL Server:
As it turns out SQL Server Management Studio (SSMS) can display many types of emoji and this is the key.
Keeping in mind that the whole thing was not written with performance or best practice in mind, I’d like to introduce the world to the very first action adventure game 100% written and played in SQL Server!
The goal here is to have a game which helps teach some basics of development practices. Interesting concept.
