As a fan of class based team multiplayer games like team fortress 2 I think the gameplay of Overwatch looks quite fun.
Nice and "timeless" art style, fast paced with a gameplay focuses on teamwork. Great!
But for "the first new ip after 16 years" the theme looks so generic. Random future people and gorilla with future tech mixed with random Robot, Reaper and a Dwarf?! Sorry but they could have just gone down the Heroes of the Storm route and put in characters from there other universes and it would be less random and generic.
So ... Gameplay looks fun, but nothing new. Setting: Meh
