I've had the rebellion beta installed since it came out on steam, but I havent had time to play it until now. I discovered that the early game feel very similar to Trinity, but late game feels fresh and fun. I was playing SP mode with 7 AI on hard. I chose my favorite faction, TEC loyalist and started the game. I liked the ability to build 2 starbases.
I haven't used the new fifth capital ship much, all I know is when I built one later, it got destroyed pretty easily. I had it retreat from an enemy fleet after the shields were quickly depleted, but it still have full Hull. Well there was aa super long trail of missiles or bullets or something following it. By the time it stopped to phase jump away, they all caught up with it and destroyed it. But it was a LOT of missiles. I think they were shot by an enemy titan.
I also enjoyed the difficulty much more. In Trinity, I used to play with 7 AI on hard and it was easy to win. I would expand quickly and heavily fortify the outer planets to prevent incursion. Then send out a super sized fleet and steam roll one planet at a time. That got pretty boring. I am surprised and excitied to see the AI putting up a better fight. It wasn't unfair, but I had to think and manage my resources. I made one ally. I got our diplomacy up to around 14 points and made some pacts.
The Titan looked cool, but it doesn't really feel right. I can't quite put my finger on it. Maybe because it just feels like a bigger capital ship.
Then my game crashed a few hours in.
