Adult PC Game: Elf Classics (Shangrlia 1 + Shangrlia 2 + YU-NO) by Elf Archive

Elf compilation released in 2000 containing 3 games:

Shangrlia 1 - similar to chess, tactical strategy, the goal is to place troops and capture the enemy's castle and not lose yours. Domik heals the troops. There is a total treasury of 20 units for the deployment of troops and each unit costs differently (from 2 to 15 units) and has different characteristics of moves and attacks. Units die or are pumped. After half an hour you get a taste, the strategic component is addictive.

Shangrlia 2 - continuation of Shangrlia 1, improved graphics.

YU-NO: Kono yo no Hate de Koi wo Utau Shoujo - A mixture of adventure and quest on the theme of parallel worlds. A young man named Arima Takuya recently lost his father, who devoted his entire life to the study of History, and died in the course of one of his studies. They had disagreements, so the death of his father did not hit Takuya very hard, but his father left his young wife, Takuya's stepmother, as a widow. Thinking about how to live on, Takuya returns home one evening and finds a package from his dead father in his room. The attached letter contains information about parallel universes and certain instructions, and the package itself contains a mysterious device that, judging by the letter, allows you to cross the borders of neighboring dimensions. Soon, Takuya realizes that all this is no joke, someone is hunting for the device, and these people do not disdain to take several lives in pursuit of it. Moreover, apparently, Takuya's father is actually alive somewhere in another dimension.
