Good browser games?

Assuming you didn't take the title of this thread to be an oxymoron, are there any great persistent browser-based games out there? I've been looking into stuff like Tribal Hero, but that's still in its early beta stages.

So, hardcore PC gamers -- any actually decent persistent browser-based games?

Oh, besides RuneScape. Had my fill over the years. :P

I already play Kingdom of Loathing.

city of steam

quake live

Battlefield 3, oh wait thats not a good one..

Gunblood

I was gonna say runescape, but looks like you've already played. Thats the only browser game I ever played.

Realm of the Mad God is quite a bit of fun. I keep forgetting about Kingdom of Loathing.. love that game. Maybe I'll make a new character and play at work :lol:

Commander and Conquer: Tiberium Alliances is coming soon.
