I like Vimeo: It has a very clean interface (at least with AdBlock, dunno how it looks without it), and the videos can be quite a nice bitrate (though it needs some precise pre-decoding to get the desired results).
Besides that, there are some awesome (short) movies on there, and it's been a great site for me to randomly browse and discover some gems (on a whole other level than the amusement of a general YouTube video brings me).
More on topic: What's the deciding factor when watching a game's video that it constitutes creative expression?
For instance, I have
one video on there of a trailer for the Alpha version of a mod I'm working on: Whereas some might see this as a "direct capture of video game play", I put way more thought into that when creating it, or at least tried to
;-). (for example, notice how I tried to line up the music to the cuts, and building up the 'tension' as the video goes on).
Another example would be (game) footage of a player who's incredibly good at the game he's playing: You know the sort of video; Raging rock music lining up the several great shots he pulls of during a match.
Would this also not be 'creative content': Imho it's telling an, albeit short, story too.
I realise I'm free to go elsewhere, but as noted before I quite like their layout (as opposed to the cluttered interface of YouTube, who recently started to also allow higher quality videos).
Though when they will be taking my video offline, I'll definitely have to be on the lookout for another host (besides my own site).
