I finished the main campaigns for both GoT and Rollerdrome.
I had a splendid time with the GoT campaign and I largely enjoyed the story too. There are some really great high moments. The final story mission being one of them .
The character missions are very fulfilling too, and have some great moments in them too. But I wasn't as interested in the ones with Norio until maybe the last 3rd of his missions.
I'm going to clean up the rest of the island, and I appreciate how this can all happen narratively after completing the main story (no loading before final mission). Then I'll move onto the expansion.
Rollerdrome was a fun time. But for the semis and final rounds I just turned on invincibility. It's a lot more fun being able to focus on increasing your score and combo without having to worry about being killed by the ai. I'll turn on the other assists for clean up cause I don't really want to spend hours upon goes replaying the missions again.
There's a slight story, but it feels like an afterthought, which is fine.
