Thanks for answering! there are lots of possible features, I'll give you a list of best traditional roguelike games to check in steam and investigate by youself to make the list of features you see easier/faster to recreate:
Elin (deepest building survival traditional roguelike with lots of random npcs and maps, customizable visual menus for inventory, spells, and abilities, this game is infinitely replayable)
KeeperRL (traditional roguelike with randomization and dungeon base building with minions, this game is infinitely replayable)
Stoneshard (most roleplaying adventuring traditional roguelike with visual menus for inventory, spells and abilities to use in map, very replayable)
Conquest of Elysium 5 (randomized exploration in traditional roguelike with 4X elements and auto battles, very straightforward, this would need a different battle system, more like hero's hour, this game is infinitely replayable)
Hero's Hour (not a real traditional roguelike is more in the veins of heroes of might and magic III, with cool massive autobattles)
Moonrise (free game in steam with the most basic traditional roguelike features including skill trees, magic system, trade, exploration, and is very cool)
I listed the best indie games with turn based movement in map wich have very beloved features by gamers worth translating to plugins for MZ
