What are some good mmorpg games that you do NOT have to download

uh 1.runescape it installs butdoesn't download and
2.roblox it doesn't download either it just installs and no installing isn't the same thing as downloading

Sherwood dungeon is completely free and no download or insallation at all and its better than runescape :)

There is also Adventure Quest Worlds and Adventure Quest on Battleon
