It's a mix from what is see, some are surprised and consider this a "departure" from other COD, other blame the design, the "same" engine, the overall same feeling, etc.
And for realistic, you know what i mean, it's not a 2025 alternate reality future with exotic background, it's a current setting with the evolutions (in architecture, building looks, weaponry, the growing place of automated vehicles, etc.) that anybody can expect. But yeah i have high standards
And i was more talking about the classic bad-ass theme + war veteran voice presentation, these kind of teasers are getting really old for me, if i worked at Treyarch for a long period to create this game, i would have wanted my efforts to be introduced in a less already-seen-240 times way. But don't get me wrong i'll try it, i love drones & "future warfare"
Let's wait for E3 to have news about an hypothetic Wii U version.
