Page 7- Game Mechanics

The game mechanics I wanna utilize is something similar to final fantasy 7 remake(if possible) or one of my favorites, God Of War mechanics. All I know is I want some action with free movement in the environment kind of like a sandbox. I also want a collecting feature to collect items with story to them for the characters; But to be completely honest if it's not gonna work I also would be interested in using a simple fighting system like the original final fantasy 7 which is a favorite but also has the adventure I'd want out of my game. This would include the attacking animations with the menu of items, attack, and magic. The open world is definitely something I'd want with a simple storytelling gameplay factor.
