The Co-op/Team shooter discussion aside - yeah, I'm disappointed as hell. I actually wasn't expecting any new IP, I thought they had just canned Titan and there wasn't even so much as a rumor that they'd been working on yet another IP. So I figured the announcement would be Legacy of the Void and that'd be it. So my expectations were low as hell already.
But another shooter? Also, it's incredibly derivative. The trailer and the world etc. look like a Pixar movie, but less interesting, and it's pretty damn obvious they ripped off TF2 in both gameplay, classes, humor to some degree and, importantly, style and substance.
Watching the trailer I recoginzed an Engineer clone, a Heavy clone, a Demo guy clone, a Scout clone and I don't even play TF2 so I probably missed some.
Also some character designs they seem to have ripped of WildStar.
Blizzard have always taken ideas, inspirations from others and refined them, most notably Warcraf and Starcraft from Warhammer and 40k. They did it well and I enjoyed their games, hell, I played WoW for 7 years. But with Overwatch they took stuff from a ton of other games and movies and it's very obvious.
I don't enjoy shooters in general much anymore, especially not team, co-op etc. shooters and I don't like team based games like LoL, Dota etc. so there was no chance at all that I would enjoy Overwatch. I'm not critizing it in that regard, just because it's not my thing doesn't mean it's a bad game, it could be amazing for all I know.
But watching the trailer I couldn't help but think "so Activision wanted a TF2 of their own". So kinda disappointed they are making YET another shooter and such an uninspiring and unoriginal one.
Also, and that's purely subjective - I don't like some of the characters shown in the trailer.
I don't like Tracer's accent, Widowmaker (seriously?), I don't like her name and judging from the trailer she's mute? Like Silent from MGS5. Reaper ... wow, original... looks and seems like a 12 year old's idea of badass, all black and red and pew pew guns and get it, he's called Reaper, like Death, woah!
The gorilla, forgot his name, seems somewhat interesting, although the thing with the glasses... seriously? He's a giant gorrilla in battle armor and he wears very easily losable and fragile glasses in combat? But yeah, that's nitpicking.
A cliche asian warrior type, some dwarf that builds/repairs his turrets - Engineer - by hitting them with a giant hammer, cause that's how that works...
Overall, the game seems aimed at a younger audience. Blizzard game usually have a somewhat comic-y graphics style, it's not that. It's more design of the characters, also the humor displayed in the trailer.
In short - or well, long - not a fan.
