GD Developers did really smart choices with this game. Pointing them out:
Wrist friendly
Back in Diablo 2, you had to click to move, click to attack, click to collect gold, click to collect potions. So much not needed clicking. Devs streamlined this by allowing you to hold down the mouse button to do all of that.
Inventory organization
The button to auto organize the inventory is very appreciated. It did not detract the original inventory and helps the player have it more organized.
Free portals
Forgetting to buy portals for town was really annoying, it meant you had to backtrack all the way to town or die, plus another slot taken in your inventory. Free portals is much better since it allows players to quickly move around and teleport to where other players are.
No gigantic maps
If you played Sacred 2 (and most mmorpgs in general), you know how gigantic the map is and how much time it took to explore everything… or ever going from point A to point B. Lots of wasted time walking. GD maps allows some exploration, but not overwhelm you with big empty open areas.
No excessive fetch quests
GD has very few fetch quests and they are somewhat reasonable (no collect 50 wolf pelts) and even the initial kill quests (kill 15 zombie soldiers/mutants) are reasonable in the sense you do not need to grind in order to complete them, just play the game and you will complete them when you least expect.
No backtracking
GD doesn’t force you to backtrack to fetch a new quest to continue the game… you can kill the warden without getting any quest, go back to town to report and people will act surprised (!) that you did what they wanted before they even asked you to do so.
No useless caves
GD does not throw dungeon/caves at you without any reason. You can almost always expect it to have a mini-boss, chest, shrine or all of them inside a cavern.
This are a few positive developer choices for this game. They did not detract from the game, rather make it more enjoyable overall.
