What was the most challenging aspect in creating this game? Poll! Greetings folks! My name is HellFell and I'm here to bring you an interesting poll! What in your opinion was the most challenging aspect for developers while creating Diablo III? Here are the options: 1. Different classes (selection, resource systems, appearance, backstory) 2. skill system (talent trees vs skill runes) 3. Graphics (technology) 4. Graphics (art style) 5. Sounds and music 6. Lore and universe (locations, monsters, story) 7. Gameplay balance 8. UI 9. Multiplayer (battle.net + coop + online only) 10. Auction house 11. Crafting 12. PvP Please choose the aspect you think Was the most difficult to implement and I would appreciate if you could elaborate on it a bit. Thank you. If you find something else worth mentioning, you're most welcome! Personally I think the most difficult thing was the implementation of the rmah. I guess blizzard went through hundreds of internal discussions on it and finally managed to integrate the most innovative trading system between gamers up to date.
