This is a really tough metal exercise when you take into account all 4 games each with their own various "favourite" play-styles. How do you not greatly fragment the playerbase when dealing with that many maps and gametype combinations (it remains to be seen how many people will even be playing this online). To me, the first thing that stuck out in your list was the lack of Big Team CTF in CE. Sidewinder and Gulch, yo. But everyone has their own ideas of what's great, so it is hard to come up with a solid list that includes the "obvious" stuff for each individual game, as well as the cross-game gametype-based playlists they've shown so far and have said is their focus. What is a sane amount of playlists to have at launch? 10? 20? Something to think about...
Oh, you're right, I did leave out the big map stuff in CE. I definitely agree with you that it's not going to be easy to make everyone happy. But I think a good way to piss almost everyone off would be to centralize everything.
Personally, I would rather see just a couple cross-game playlists in favor of more single-game ones, but that's just me. I like the idea of switching games on the fly, but I think the novelty of that is gonna wear off pretty quickly.
