I just loved the gameplay in Anthem. Not particularly the loop, the grinding, the enemy "variety" or mission design. But the base of it all, the flying and hovering and fighting. Especially the idea of turning the common formula around by making the combat ability focused with guns being more like support items, instead of focusing on shooting and using your abilities in between (like in Destiny 2 or The Division, for example).
The game really is the prime example of "wasted potential" when it comes to video games.
I just wish it would've been developed by a company with more experience in online multi-player games and released by a publisher that's less egregiously openly focused on maximizing profit above everything else like EA.
