What type of art style would you like to see in zombie open world survival game in 2D TOP DOWN perspcetive?

 1. pure pixel art, images max 64x64 on big furniture 32x32 items and characters.

Pros: you make it easy, if you learn a bit you can make it very nice and it is super fast! You can even make one man project like hotline miami]

Cons: you cant put many detail into it. 

2. Drawn style: Resolution is max 256x256 on big furniture 128x128 on characters and 32x32 for items. 

Pros: I cant even seem to fins such game from top so it qould be Really unique. You can put much detail like fork in table.

Cons: Harder to make, it requies only ONE artist since every artist has unique drawing style. Characters are MUCH harder to make and animate.
