If I may, I might as well throw in my input concerning the two in-development LEGO Universe RPGs. From my understanding, most former LEGO Universe players, as well as those who would have been interested in the game had it not met such an untimely demise, would essentially like to pick up where the original LEGO Universe left off, and only then from there, much like LEGO Universe, the RPG could receive periodic updates to include new worlds and new quests as the hosts see fit, which is what I see in the RPG proposed by Jacks and Brikman McStudz. To start off the RPG right away with such a drastic change from the original, such as the corruption of Paradox and Venture League in sonyaxe's RPG, might put off some would-be players.
Back in the days of LEGO General Discussion RPGs, I actually saw that one criticism of Dino Attack RPG was that it was no longer focused on Dino Attack and the players were fighting Maelstrom instead of dinosaurs. Granted, this is a bit of Did Not Do The Research, since the critics were not actually DARPG players and thus did not know that the Maelstrom's involvement in the RPG was directly related to fighting the dinosaurs, but this just goes to show that if you stray too far from the source material, you run the risk of losing your audience.
As a former LEGO RPG and LEGO Universe player, if I were to hypothetically join a LEGO Universe RPG, I would be interested in playing as Captain Greybeard the Venture League Buccaneer, who was my primary character in the original game (not the same Greybeard who appeared in the Dino Attack RPG). Venture League suits Captain Greybeard the best, so he'd be unlikely to be a member of Sentinel or Assembly. However, if the entire Venture League has been corrupted as it is in sonyaxe's RPG, then that means that Captain Greybeard cannot be a hero in this RPG and would be immediately branded a villain. If I had a Paradox character, the same would apply. But I don't want Captain Greybeard to be a villain; I want him to be a hero. This would make me less likely to join sonyaxe's RPG. Since Venture League and Paradox are still heroic factions in Jacks and Brikman's RPG, I would be more inclined to join that one.
Although, if Jacks and Brikman feel the need to start off with "something completely different" for their own RPG, I would recommend making Stromlings a playable faction. I have a feeling that the corruption of Venture League and Paradox in sonyaxe's RPG is to give players the chance to play as the villain if they so choose, but the simpler way to go is simply to keep Venture League and Paradox as heroic factions while allowing players to play as Stromlings. And the plus side of playable Stromlings over corrupted Nexus Force factions is that Venture League and Paradox can still be heroic, but Stromling players can choose to play as "fallen" Venture League or Paradox (as well as Sentinel or Assembly) members. This allows for more choices in character creation, without going into the "too many choices" pit that the Pirates RPG and Castle RPG proposed by Atton Rand and imperial officer in the old LEGO General Discussion RPGs Topic fell into, since it can still be easily divided into two generalized factions: "good" Nexus Force and "evil" Maelstrom.
Of course, seeing as I'm unofficially retired from LEGO RPGs, everything that I said about joining a LEGO RPG must be taken as theoretical, and also remember that not everyone has the same tastes as me. But, I figured that, while I'm still here, I might as well toss my two cents into the wishing well and hope that said well isn't actually the Kakariko Village well inhabited by a Dead Hand that wants to eat my face.
Also, I must also throw in my support for the notion that LEGO RPGs do not need to be connected to the Dino Attack RPG. The RPG must be able to stand on its own merit, not on that of a previous successful RPG. While the Dino Attack references might appeal to former DARPG players, they will also turn off those who did not participate in DARPG. This reached a ridiculous extreme in Atton Rand's proposed Castle RPG, which literally had the plot of "In 2010, these castles and kingdoms will be wrecked by dinosaurs, but until then, have fun!" Remember that, while Dino Attack RPG did have Alpha Team: Mission Deep Freeze RPG to thank for its early success, I felt that Dino Attack RPG was only truly successful when it stopped trying to be Alpha Team RPG and started to be its own thing, starting around the beginning of the Goo Caverns story arc. Also, while Alpha Team RPG: Ogel's Last Stand was intended to bridge the gap between Alpha Team: Mission Deep Freeze RPG and Dino Attack RPG, it felt rather odd to see most of the cast as "the cast of Dino Attack RPG, who all just happened to be Alpha Team agents!"
