Since it's not under NDA in its current Beta form, I've got plenty to say on this.
Breakpoint is way less tactical than Wildlands - and even despite my Wildlands complaints about that being dialed-back a bit, I still liked that game. Wildlands was still ambitious as hell and trying a ton of new things (i.e. UbiSoft open-world stuff with AC-like icons for side-stuff everywhere; GTA-style vehicle driving; and mixing GR tactical stuff); things that I feel should be expanded on with Breakpoint. I might not have had entire control over my AI squad in Wildlands, but you still have some control...and that was still enough.
Also, guns don't feel as moddable either in Breakpoint. You could easily swap-out pieces like scopes and things back in Wildlands. You had less guns in Wildlands, but more mods. Now, it's gone the other way with Breakpoint - as you have more guns, but less ways to mod them. And these guns seems to be littered all over the map to find, too.
Also, the storytelling, narrative, writing, dialogue, voice-acting & cut-scenes - don't seem to be anything special; and that's a problem, as it's trying to also focus on this stuff. At least if this stuff was good-to-great, I'd be fine w/ this stuff being here in Breakpoint. It's maybe passable...and that's about it. And you'd think with this more story-orientated attempt here, it would make more sense in a game with an offline option, but that option isn't here either. At least with Wildlands, you could play offline or online; up to you.
At least with Wildlands, this story-stuff was straight to the point and quick (like Skyrim often does) - and then you got going, so this stuff didn't get much in the way...as you did the missions, often having context via logs/video/audio/etc in Wildlands if you wanted more info and context. With the online-only factor now in Breakpoint, I could see other players...really getting annoyed w/ these cut-scenes stuff not told to them by other means, interrupting the flow of gameplay & gunplay; especially since these cut-scenes & narrative aren't even that good.
Breakpoint also runs like un-optimized crap too; it's even worse than Wildlands, AC: Origins, and AC: Odyssey here. On High at 1080p, it runs anywhere from 30-60fps on my laptop (i7 7700HQ; 6GB GTX 1060; 16 GB RAM; W10 x64). Game looks "meh" below High (i.e. same problem AC: Origins & AC: Odyssey had). It looks amazing at High, but it runs like crap; had to lock it down to 45fps to keep it somewhat stable. I hope they can fix these performance issues before the game comes out.
It also seems like UbiSoft wants to stick The Division ARPG-looter elements onto everything. First The Division; now AC with Origins & Odyssey; and now GR here with Breakpoint. With leveled-enemies, it makes the game less open; as some areas are just foolish to run into. This wasn't as much of an issue in Wildlands. With your gear having levels now in Breakpoint, you need to now pay attention to your gear and make sure it's equipped and leveled properly too - b/c that can be another factor, if you run into enemies and/or an area...and you're both leveled similarly, you'll actually have a chance there.
Combat still feels and plays fine. Gunplay is still good & feels right, like it was in Wildlands. I do like the additional realism elements of you hobbling and having issues walking/running, if you don't heal & bandage yourself. That realism stuff is actually welcome to me, adding an interesting element to the combat. But, losing the tactical stuff hurts - as having the injuries and tactical stuff together could've been something really interesting & special.
In so many ways, this no longer feels like a GR title. It began to stray a bit with Wildlands, but it went even further here with Breakpoint. It should've just been called Tom Clancy's Breakpoint.
This is an online-only game and could be living & breathing, so I do hope they can overhaul & add more tactical GR-stuff stuff in say patches/updates, DLC's, expansions, and/or something. And I do hope they can optimize this game b/c...it sorely needs it.
But, given what I've experienced so far & given that the game's out in early October (next month) - yeah, I don't have my hopes up here.
