Some thoughts on the new interview:
Both sub-factions share all the ships and abilities from Sins, plus a new capital ship that launches pods full of marines to board and capture other ships or destroy them from within
Well it looks like the ship boarding stuff so many people requested is going to be implemented after all. Don't know if I should be happy about this or not. I will be, as long as you will not be able to capture Capital ships.
The Pirates won't attack those Rebels no matter how much bounty is on their heads, and a Rebel player can even stash valuable ships smack in the middle of the Pirate base for safekeeping. As a bonus, the Pirates will contribute ships to the Rebel fleet, complete with amusingly tongue-in-cheek pirate voices.
Now this is just pure epicness. Pirate voices! So many people have been waiting for this!
The Advent Loyalists are on a vengeful rampage and use their psychic abilities to their fullest to assimilate enemy ships. Their planets automatically spread culture without the need to build structures, and their Titan can mind-control an entire planet, permanently taking it over. The Advent Rebels, who suspect that their collective consciousness has been corrupted, have the ability to resurrect destroyed enemy ships as their own, and their Titan can consume other friendly ships to keep itself alive.
This seems very interesting to me aswell. Especially the ability of the Rebel Advent titan. Though it is of course questionable if eating your own ships is such a good idea...
Finally, the Vasari: the hyper-aggressive Loyalists can no longer sit still and wait for the still-unnamed threat that chased them into TEC space to catch up with them, so they're focused on mobility. They can upgrade their capital ships to produce money, supply, and research, and their Titan can function as a mobile capital world (and also summon Dark Fleet ships). Once they have that, they have no more need for planets, so they can strip them of every shred of resources and leave behind nothing but a dead, uninhabitable asteroid.
Now that's also some sweet stuff I really would like to see ASAP in the beta. Also the fact that Vasari capital ships can act act as research stations and have them generate credit income is really interesting.
(...) games will be over much more quickly than vanilla Sins' multi-hour battles, which will make it much easier to get your friends to commit to a war for inter-stellar domination.
I am glad multiplayer will become more accessable for everyone. Often I do not have enough time to play Sins online for a few hours straight, so I mostly play single player mode. Slaughtering Unfair and Cruel AI's is starting to become a bit boring by now though, so I hope to really get into the multiplayer scene when Rebellion is to be released.
All in all, I am looking forward to the beta even more now...
