The game cost money would somewhat balance things out, but those people who can't afford paying anything won't have the opportunity to play, but I actually think that I can just go download a cracked version though. So it would be either you have money or you cheat - you can play the game, instead of you have money or you cheat - you win. I actually approve this myself, but they already made it from purchase to freemium so again, not many chances they would revert that.
I was implementing vanity as a secondary equipment slot actually, that means it will replace the look of armor, but have no effect, sort of like when you wear casual clothe outside a bullet proof jacket, cover your diamond helmet with a hoodie (and making the armor transparent).
For the rest, nerf armor and lazer minigun FTW!!!!!
