Alright, here is a list I made of random things I would like to see in Diablo 3:
Inventory - Although I am glad to see the grid system go I hope the developers are not planning on making the diablo inventory system similar to the one in WoW. I think I'd like to see a system where you have certain "boxes" on your inventory screen which can only hold specific items. Maybe 5 boxes which can only hold weapons, 5 boxes which can hold only armor... something like that.
Armor dying - With loot being the basis of a Diablo game I think this would be a cool and fun addition.
PVP - I wouldn't mind if pvp was completley removed from Diablo 3. I find that PVP primarily adds frusteration and takes away from the immersion and epicness of a gane which is entirely PVE based. I'm sure pvp could be implemented in a way thats suits the needs of everybody but I'd rather the developers spend all their effort working on great PVE.
End Game - Instead of requiring players to farm the same bosses over and over (Baal) in hopes of drops I think it would be interesting to add randomness to the endgame of Diablo 3. How about a dungeon where players summon a random looking boss with random abilities? This would keep the endgame refreshing and require players to continually become more skillful as they are required to adapt to different variations of this boss.
Economy - The economy in Diablo 2 was horrible. Gold was useless and duped items were everywhere. Hopefully there are plans to ensure the economy in Diablo 3 will be better.
Things in Diablo 2 which Diablo 3 shouldn't change:
- Waypoint system
- The wide variety of loot
- Unique classes and cool abilities
- A variety of monsters
- Story driven quests
- Difficulty curve
- Different and unique environments
Finally, I'd just like to say that I'm really happy with the way Diablo 3 is currently looking. I think the health globe system is genius, and I'm a fan of the art design. Keep up the good work!
