Played another game. Played another game. Played another game. Played another game. Played another game. Played another game.Played another game. Played another game. Played another game. Played another game. Played another game. Played another game...Slept.
Then after about 4 hours of sleep, I finally got to process what I had played....
This game is masterfully built and goes against all common conceptions of modern games. You can tell games that are built by committee or built to hit bullet points or built mostly based off market research....Overwatch is not that.
Overwatch is a no-nonsense, no-frills arena based combat game. I can't even say arena based shooter, because half of the characters don't even have a primary attack! They are able to cutout so much of the BS surrounding modern games with gun unlocks, prestiging, K/D, camping, spawn camping....all by simply offering a game that is completely, and I mean COMPLETELY, built around the characters instead of everything else that gets in the way.
There is a leveling system, but that simply unlocks a new loot chest with each level, which just awards you cosmetic items. This barebones progression system might hurt the game's longevity, but the pure joy you get from learning and getting comfortable with each character far outweighs any market tested game mode or RPG mechanics I can possibly think of.
I hate lazy MOBA comparisons for this game, as most people that make those are simply confusing it with Battleborn, but I do believe they took the nuances of hero combat in MOBAs, and brought that to an arena combat game, flawlessly. There is a reason you only need one map and essentially one mode in MOBAs, it's all about the characters and the interactions between players at the most basic level, and that's exactly what Overwatch is.
I'll stop speaking in generalizations, I just don't know any better way to describe something that on paper has so little to offer, but in reality offers such a wide variety of experiences, that anything else would just be noise.
