One of the things that I felt had improved was the character development. No longer restrained by the mystery surrounding the card game in the first season, characters such as Ruko, Tama, and Ulith are developed quite nicely. While other characters are pushed aside to make room for that development, it didn't bother me too much.
The other thing that developed pretty well is the storyline. There were times that got even darker than it already was and that kept me going to the next episode to find out what happens next. There is also a philosophical theme about choices that develops to make the story richer.
Other than these things, everything else is about the same as the first. The art is still garish yet sometimes gorgeous. The sound is still soft electronica that provides ambiance to battles. The battles are still thrilling.
Overall, I think I enjoyed this season even more than the first. If you enjoyed Selector Infected, then do watch Selector Spread.
