I was trying to think of which games created certain mechanics that became popular and copied by future games in the industry.
The most famous one that comes to my mind is Assassin’s Creed, with the tower climbing for map information.
A roguelite is ostensibly something that has enough features of a roguelike to be noted, but not enough to be considered one. And I’d argue there is way more to what makes a roguelike than permadeath with no meta progression.
Also Slay the Spire has less meta progression than Issac. Hades is in a whole nother ball park.
