I don't hate the franchise, but the last one I enjoyed was BF2. I own BF3, played it a grand total of around 15 hours. Maybe a total of 25 hours of BF4 (which I also own). I skipped BF1.
Not sure if I would be interested in another one. Maybe one set in the future, they did that already of course with 2142 but I'd like to see that happen again. I'm tired of WW2 stuff, had more than enough of it over the decades (and playing something like 900 hours of Day of Defeat was amazing but I don't need that much more). The only way that it might be interesting for me if it's set within the WW2 period is only if they do a Steampunk spin-off alteration of it in the veins of New Order (Wolfenstein). But despite all of this, I would actually like it if they really dared, if they got super bold and went a completely different direction. Like... I don't know a Battlefield game with Mecha warfare or an alien invasion (screw zombie apocalypse). Or heck, if they give us some cell shaded or colorful and humor-filled game with a lot of focus on single player maybe in the veins of Borderlands or... I don't know. Something new, and fresh. But no... I know, they'll stay with the traditional BF formula.
