I would love to see a more realistic survival game with the element of "only the strongest survive". By this i mean, perhaps an injury that is sustained will be with you for quite some time. A limp from after breaking a leg, cant use a hand tool after breaking arm, etc.
But the biggest thing id love to see in Ardem is enemy prisoners. If you take a prisoner, from another faction, they are unable to break out of handcuffs, you can put them in cars, or jail cells, etc. Im thinking of in walking dead with the different surviving groups and how they would take prisoners for ransom or leverage. It would heighten the RP aspect for sure!
Honestly, if you guys released the game today, it would be better than every other zombie survival game.
