Bought a few days ago, and I have to say, I absolutely love this game.
First off, what they've done with the whole scoreboard and everything so closely aligns to how I want to feel playing video games: upbeat and positively focused. I mean, they don't even have a death counter on the final scoreboard. Every single stat is just a "this is neat, good job!" I honestly think it makes the game a lot less toxic, too; I haven't felt the need to mute a single person yet which is super rare for me. Heck, I haven't even turned off voice-chat.
Second, it really fits what I want in an FPS game. I remember when I first started playing FPS games I'd try to be all "ninja-like" and sneak up behind people, and just have fun. Being silly doesn't really work in most competitive FPS's now. Overwatch, however, I can pick a fun hero (read "Tracer"), and literally just teleport behind the sniper, while still being a balanced and fair game overall. This is basically everything I could hope for in an FPS game.
So yeah, I'm having a lot of fun. I'm definitely not a pro at FPS games, but you can add "QuinnRi#1683" for a good time.
