Cake-Day fun(?)

Yep, today is my Cake day... blah blah.
Since I'm more or less broke/saving up so I can move out. I have a "fun" question for you.

First - Think of your FAVORITE game (Or series if its a more general thing). Generation, genre, iteration doesn't matter. Just pick one.

Second - Pick something from said game, grapics, audio, gameplay, dialogue... your choice.

Third - Change that feature to something equally as great, if not better. Keep in mind the key word is CHANGE! If that change makes your game similar to another, so be it...

Finally - Others, if they so chose, can comment on your idea. Is it good, bad, or just plain silly. BUT DO NOT BASH PEOPLE FOR LIKING X GAME OR LIKING X FEATURE. Creativity is key... not being a dick.

My pick/Example:
My favorite game is Dead Space. Feature: Isaac's and his Rigs. - I love the rigs Isaac wears... but just buying them from a shop feels a little boring for a survival horror.

Lets spice it up. Dead Space is supposed to be a survival horror game right? Well, lets make it more survival horror with a rpgish twist. Isaac is a C.E.C. Engineer, he has the knowledge and skill to create his own rigs from scraps either found, stolen, bought, or even killed for. You spend time at a bench creating your new custom rig some pieces you found, which may add more ammo storage but you lose air space or weapon slots for it. While other armor may make you light and nimble you obviously lose protection. Etc Etc.

Now lets see what you all post.
