Dai influence?

Besides the fact that most of these similarities are entirely superficial (and based solely on a minute of actual gameplay), you have to bear a few things in mind:

1. The two games use the same engine, so expect the camera to feel similar (you actually might notice how a lot of Unreal-based shooters have a similar floaty feel)
2. We didn't see any combat, so of course we won't see the distinctions (the camera might pull in during combat for example). In fact, I remember a number of complaints that ME3's camera was too close, so this might have been a crowd-pleasing move on BioWare's part
3. ME:A is, to a much greater degree than ME2, an exploration game, so It should play differently. The effect of this shift is that we're going to see a lot more exploration tropes like dungeons and platforming. If that's similar to DA:I, that's merely a product of the greater thematic similarity between the two games, not necessarily an agenda to homogenize their mechanics.

However, I wouldn't be at all surprised if we see a number of DA:I's mechanics make an appearance in ME:A. They're made by the same developer on the same engine. Sharing is just economical. What I would hope is that DA:I's overall design philosophy isn't carried over. It probably will be given what we know of ME:A already, but I can still hope.

They were not gripes more observations. I'm hoping we go into a more open world setting with gunplay similar to dai archers

I just see a lot of trespasser influence including the fliating globes

Never liked 'shooters'...

RPG with guns? That I can relate to

I just want it to not be to slow. If I can't Biotic charge and shotgun somethings face off effectively I'll be disappointed. They've mentioned Biotic charge before so pretty sure it's in. They've also mentioned it's still a cover shooter at heart so... yeah I dunno. Charge + shotgun all I want, everything else is secondary.

I keep getting the vibe that they're trying to make this the game they originally wanted Mass Effect 1 to be but fell short on in the exploration aspect. If they succeed at that we'll see when the game comes out.

As others have said the cutscene was heavily modded so as to not spoil anything and was just a tech demo to show off some fancy new tech they have for the PS4.

Plus the engine being the same, but I'm thinking given that Frostbite was originally developed by the people who make Battlefield that it'll be better suited to Mass Effect than Dragon Age. I think Dragon Age just had to use it because EA wants to use their own engine for everything now more so than it had any decent merits for a RPG.

This times 1 million. 

I think the engine was well suited for any kind of rpg

Is it pre alpha/spliced footage?

With no me3 experience how much Rpg Elements were there compared to dai such as puzzles I'm getting a away team trek vibe

Has to be valid reasons why they introduced jet packs and climbing

So Borderlands?

Hunter : I wouldn't say the Mako is sacrilege, I just think it's the thing people point at and go 'it's why its bad' when its not. It sure as hell didn't help what was there that's for sure. But it wasn't 'the problem'. It was just the awkwardly driving thing that made the real issues shine more crappily.

Like you said there was 2 base types, 1 or 2 cave types and that was about it. Was always 1 on every area for no good reason other then to have it. Wasn't anything else beyond 'collectibles' pretending to be a mission (that you don't pick up from ANYWHERE, it just exists). Add to that the 'Simon Says' mineral gathering for no reason other then, again, collecting stuff aaand yeah. It all felt pointless and uninspired, sadly.

Mako was just a kinda awkwardly controlling, semi-slow to start vehicle that kept us from having to 'walk' all that crap. Mako looking faster and funner is nice to see. But if those maps aren't designed with fun driving in mind it wont help to much. I have faith they wont re-do ME1 style planets though.

-edited for clarity who I was responding too-

Not tried, will check...

There's actually a mod for that (that ones links to the one for the Pre Sequel, but every entry has one). It only changes the camera perspective though, so if you care more about TPS conventions (like cover and such), then it won't really help you there. Otherwise, it's fairly robust.

The recent Deus Ex games are actually closer to RPG shooters with the feel of a 3rd person game. It's first person until you get into cover.
