multiple terrains so a whole world can be built: desert, forest, castle, dungeon, beach, grasslands, town, village… etc
also animated tiles: water, lava, quicksand, moving trees, grass, torches
characters with 4 directional attack animations. This is a massive one most character packs have walking in four directions but attack only left and right.
Also multiple animations for characters, sitting, lying down, fishing, jumping, using a potion bottle, pick up, put down, throw, carry.
Icons and sprites for items, weapons, shields, money, health, ammo.
there’s a lot that can be used in a game.
