I have some new suggestions, these are for the menu when creating a new game.
-The Possibility of Configuring the Loot of Each of the Items.
-The Possibility of Setting the Difficulty of the World:
♦Enemies Have More or Less Life Depending on Their Difficulty.
♦ More Or Less Damage To The Player From Enemy Attacks Depending On Their Difficulty.
Other Good Ideas:
-Day, month and year of start:
♦Being able to start the game on December 24 in winter.
-The 4 Seasons and Climate
(Normal, Sunny, Cloudy, Rain, Snow among others)
(I don't know how much of this weather will affect the FPS)

Get to know the game and contribute new ideas.
