I tried it a bit to see what's up.

What's new: it lives inside a browser window. No flash or silverlight, though: you install a plugin for Firefox or IE, and BAM! your browser becomes a slow host for a 10 year old game.

Yes, because the game is... Quake 3 Arena inside a browser window.

Pros:
- it's free
- it runs on my machine (damn, it's Q3A after all)
- you can play the training stage while the game downloads the rest of the media contents
- when looking for an online game, it suggests games you will find challenging with your skill level (adaptive shit)
- it's Q3A

Cons:
- it's hosted in the browser, but still needs you to open ports on the router (no http tunnelling or other junk)
- long queues before you can download or join
- still lots of crashes :(
- it's Q3A

Discuss.
