People should play the open betas which they've made it VERY easy to access. No money, no preorder, just log in. The only downside is usually these beta tests have limited playmodes/maps/weapons which is kind of a fake way to test the game outside the very basics of it.
None of what I watched really wowed me at all, it looks good graphically, and the UI seemed similar to BF3/BF4, but there wasn't anything that really drew me in. One of the problems is that a lot of the streamers they got to demo them aren't BF players or tactical players. Either scream = funny streamers, popular because attractive streamers, or W-key CoD babies. The streamers I watched all seemed to congregate to the TDM mode, which is the absolutely LEAST interesting playmode to BF players probably, and in the Conquest modes didn't do anything but rush in and die over and over with SMG's/shotguns. Zero competent vehicle play, testing of gadgets, or actually trying to "win" the game. Just CoD-mode in both TDM and non-TDM.
Means that hopefully there's more to it than that and we'll get to see for ourselves for those of us who actually like the complete BF package instead of zoom n boom. But honestly if that's the crowd they're catering to, it may be as much of a letdown as 2142.
