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.

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.
