I'm almost done with Destiny 2. Bungie greedy apart, the gameplay just don't challenge me enough.
For long, brainless grind sessions the gameplay works, you lazily aim for the weak spot, collect geometric forms and get some upgrades now and them but I simply can't die on solo content unless I walk off a cliff.
I guess perhaps playing with a controller the game is somehow challenging but I play with mouse. To compare I find playing World of Warcraft more challenging and WoW is as casual as it gets
Like I said on Twitter, the gameplay needs more Genji, less Soldier 76 and the only thing I want now is to get the gun Better Devils and I'm off to try Elite Dangerous.
