Agreed
I don't get how the titans will work, isn't it 40K lore that they're 400 meter tall (give or take)?
How will that fit on a map or will they finally allow enormous zoom if so will that make the game less squad based?
Edit:
Seems like all things 40k there is different lore to their size
Or
I prefer the super massive ones. I fail to see how a few squads of 45 meter tall war machines could topple an entire planet
For now, I'll wildly guess that if they want to 'properly' show [big] scales in the game (Infantry to Vehicles, to Buildings, to Titans, etc) then they will almost certainly have to allow us to zoom all the way up sky high (probably literally so). They might go with a camera / zoom / scale system similar to the one in
Supreme Commander. In fact, at least from the RTSes that I've played, the only such games I can think of that did massive scale battles and used a far-zooming camera system are Supreme Commander and the Total War series (for the dynamic field battles of course). Additionally, they might allow full 3D camera with rotations as well, and not fixing the camera in a bird's eye view all the time (such as in the Total War series).
Time will tell, but I do think that we might have something in the veins of Supreme Commander. And, side note regarding the camera, interestingly enough, let's remember that we can already rotate the camera pretty much in full 3D space during skirmishes in DoW1 for example.
Now, regarding the Titans and their sizes. It's true, there's no real, official, centralized database that states exactly how big and tall they (can) get. There's various sources, and it's pretty much free-for-all for authors of WH40K work, probably as long as you don't just straight up exaggerate the statistics of "your" Titan(s). I know there are authors of WH40K novels that merely invent sizes (because they themselves don't have references, they have no other choice), and sometimes the exact same Titan class / model in another book will be given a completely different size (and even different armaments) because that book's author also had no idea and just went guessing mode on it.
It's a bit like the Star Wars' Expended Universe, as long as you sort of remain within a certain framework you kind of just invent what you want, and what you have to for your story-telling (species, ships, weapons, etc). In the end, there's no 'enforced' and official Titan specifications (not that I know of anyway), so we ultimately end up with - literally - individual takes on them by various sources and authors. So, even Relic Entertainment will have to take some guesses here and there for their "own versions" of their Titans in the game. If they wanted to, they could just give us a 5 kilometers-high Emperor Titan, but that wouldn't make
that Titan any more 'official' than any others before in other sources.
In the trailer, for example, one Titan I can easily identify is the Imperial Knight (it's the two Titans with a chainsaw on one arm and a cannon on the other; and side note, that type of weaponry combination on Knights is not standardized, it can be modified based on situational needs before deployment). The Knights are 'known' to be smaller than Warhound Scout Titans (that's what I meant by 'framework' earlier, there's sort of limits you can't go beyond because they've been established through and via enough sources over the years to be considered 'official', or 'official enough'). Then again, 'smaller', but by how much? Well, you can vary that, as long as you don't make it as small as an actual infantry unit of course, and not taller than a Warhound... then again... what is the
minimum Warhound height? We don't know. Yeah, it's a mess.
Another note, coming back on the trailer. The Imperial Knights attack what looks like to be a trio of Eldar Wraithlords. So, I'm not an expert on the WH40K universe, I merely happen to LOVE it. But, technically-speaking, - and any actual knowledgeable person with enough 40K lore expertise correct me, if I'm wrong - Wraithlords are NOT Titans (at least, I've never seen a source referring to them as such, but maybe they are, not 100% certain on that). However, that I do know, they ARE taller than Imperial Knights (another sort of "known" within the Titans specifications framework of the WH40K lore). So what I'm trying to say here is that at least only going by the trailer, we might get smaller-sized Titan classes if we do get them, and might not have the big(gest) ones.
One last thing though, when it comes to Eldar Titans... my problem is that many of their classes are lookalikes and can be identified mostly going by their height alone. In the trailer, to me anyway, it DOES look like they are Wraithlords... BUT... they also do look like a Wraithknight. The problem is, a Wraithknight is probably a good 8, 9 or 10 times taller than an Imperial Knight (and the trailer clearly demonstrates that the Knight jumps a bit to cut through the Wraithlord, simply because it happens to be about the same size, which leads me to believe that indeed it's a Wraithlord, and not an actual proper Eldar Titan per se).
Then again... I'm no WH40K expert on the subject and I'm just going by my own knowledge. If anyone knows more about this Titans size thing, let me (us) know. It's fun speculation for now I guess, if anything. But ultimately it might indeed have an important role in game-play itself (and related to the camera / zooming system they'll use if they truly want to properly represent massive scales on all fronts, and not just in terms of number of units on the field).
