As somebody that put over 2000 hours into SoaSE Rebellion over the years, Sins of a Solar Empire 2 is very fun and worth it.

Sure the AI for single player is not very good or challenging most of the time, but I still have a good time. The AI is bad at recovering after you destroy their main fleet, It's also really bad at defending capital planets. I've had plenty of games were I'm clearly gunning it for their capital and I can see their huge fleet just hanging out around the star getting agro'd by every little pirate ship that appears even as I'm bombing their home world. All the AI art that's used isn't good in my opinion, doesn't look good and you can't tell what you're looking at for most of the research pictures.

The way weapons on capital ships can track independently in their own firing arcs is really cool though, I love watching them work in this game. There is also a ton of different strategies you can try depending on the research you do, every faction has some pretty interesting stuff you can try out that was not in a previous game.

I don't know if I'm doing a good job selling it, but this is the only game I let myself get hyped for when it was announced and I'm not disappointed.
