Hey guys and gals, i thought i would suggest http://playensemble.com to you, its reasonably early open beta, it includes Gathering resources, Building, PVE, PVP (manually rewarded) questing AMAZING community, frequent live streams (multiple per average week) showcasing game creating, brainstorms with Devs and the creation of their comic.
Map size is 400 million x 400 million (or maybe it was billion).
Each player currently has 3 levels Hero, Gathering, and Building all of which can be built in different ways depending on your play style.
Exploration plays a large role in this game and more features are planned for both near and distant future updates, some planned features include territory/land control, pets and mounts, more explore-able areas, and recruit able units for multiple purposes including base defense while you are offline, will be a perfect game for guild.
I love this game and the Devs [Edit: Ian Megan and Jesse] and hope some of you will too.
