I know its not out yet, but there have been very few press releases about a new game that Jagex is releasing. As they are the creators of runescape I know you are all thinking I should just shut up now and stop before I waste your time but I'll carry on anyway.
They are meant to be releasing a new game they will be calling MechScape (bad start already I know) The tiny part of genuine news about this game was in an interview with one of the developers and he said that it is going to be using the same technology that they are using on RS so it will be purely browser based too. He also said (as you might have guessed) it will have a science fiction theme. Most importantly that he said was that it will be more complex, and targeted at the older generation of players.
It is expected to be released in Q1 of 2010. I know this is still a while away, just worth keeping an eye out for it if you can, I'll be back in Africa by that time so I will not be able to remind you guys.
Tomorrow I'll make a post about another game that fits all your reqs for a guild game, yet it is not browser and not f2p sadly... no cash shop though and extremely heavily clan based gameplay. just check it out now before I post if you like (quite pricey though for now no way to soften that blow, unless you are a WoW player)

Edit: One more thing! The Europe Server came out first, by about 5-6 months, so maybe things are better established on that one. I got no Idea how it works if people from the USA can join the Europe server or not. Personally I would prefer to join the Europe one if/when my computer returns from the factory... - purely because of my experience with young american players, I know theres immature annoying players all over, I've just experienced most are from america (maybe those are just the ones I understand) but the thought of being in a server that is only Americans just fills me with dread!
