During Ubisoft's E3 conference they announced they'd be bringing some games to browsers. They talked about Settlers Online (which I believe is already going) then ended with this:

Finally I'll be able to fly into a fit of rage without needing a 360 nearby!

...will they be free? I'd be fine with a short advertisement in between levels if the games themselves cost nothing.

Not sure. On further examination it appears it might not be on browsers. My net connection was buffering the conference a bit and I apparently missed some Trials footage before it said "games in your PC browser".

Thought it was a bit odd nobody else was talking about this. :(

I'd be more happy if they just released a normal PC version.
