Just need visual proof of Sludge now... (sorry sleeve

)
It's interesting to hear that they are still conceiving their WFC game ideas from Gen1, right down to their visual appearances (which we've seen are completely different to Prime & Movie aesthetics). It's like the gamers are long time fans and are doing this game for fellow Gen1 fans, but then the story these characters are in ends up being shoe-horned into what Hasbro currently wants as it's story universe to be. The game designers even had to work hard at convincing Hasbro to allow them to use the Dinobots because they don't fit within their "grand plan".
(it also sounds like they might actually call the five dinobots by their original Gen1 names, instead of the Hasbro "politically correct on every continent" names - but is still too early to tell, especially if toys are likely... it has been a while since Hasbro managed to give all 5 classic names out to the right dinosaur forms)
The concept of Grimlock transforming when he gets too mad reminds me of an old Hulk game, which you had to keep his rage down in stages he had to infiltrate (avoiding electric traps & troops). I can't remember if you also had to keep him raged when needing to use the Hulk... but I'm thinking that may be the case in this game when using Grimlock. If you need to use him in robot mode, he can't be allowed to overheat (physically, like with an onscreen rage/heat meter)... but then when you need to take on a difficult situation or opponent, you gotta get him worked up to make him change.
Ah, just got to the 13minute mark on the video, and they ended up saying something similar... he has a rage meter (like the special ability feature in Campaign & Escalation), but you still choose to activate it, it isn't automatic.
I wonder who the blue robot is that's on the far left of the wall in the first video. If they've redesigned the main characters like they did with Optimus, the colours look like Thundercracker, but looks a lot more impressive than the regular seeker design.
A closer look at it, I don't think it is Thundercracker... so looks like an interesting character.
