First of all, I like your list. I read it completely and checked several.
I hope there will be a few games I play longer then a couple of weeks.:3
I try a lot of games just to see if they are worth playing. Most of the time I play at work >_> because at home I don't have the time.
Therefore I prefere browsergames where there is no download.
I can't find many (good) browsergames in your list.
My favourite (browser) game is Freekick: an online football management game. I play it for 2 years now and I find it very realistic (and much better then other simular games like Hattrick, Managerzone, Sokker, PManager, etc...)
