No Stage Selection for 1v1 online. I don't always want to play FD.
The game looks really good, and the Smash series looks like it will continue its tradition of going all out in terms of modes and characters. I'm still bummed that they can't get it out quicker (I'm greedy I guess) but I'll be playing these games for 5+ years so a few months isn't a big deal.
My one complaint is the "For Glory" mode. The issue is that, as good Smash players know, FD is NOT a balanced stage. Certain characters, like Ice Climbers, Falco, or Diddy Kong, have an advantage on FD, but others (Zero Suit Samus, Squirtle, Metaknight) don't do as well. I also would have liked a more ambitious ranking system.
Overall though, 9/10. It's shaping up nicely. I just wish it was "winter 2014" already.
