Project: Gorgon is a 3D fantasy MMORPG (massively-multiplayer online role-playing game) that features an immersive experience that allows the player to forge their own path through exploration and discovery. We won't be guiding you through a world on rails, and as a result there are many hidden secrets awaiting discovery. Project: Gorgon also features an ambitious skill based leveling system that bucks the current trend of pre-determined classes, thus allowing the player to combine skills in order to create a truly unique playing experience.
The Project: Gorgon development team is led by industry veteran Eric Heimburg. Eric has over a decade of experience working as a Senior and Lead Engineer, Developer, Designer and Producer on successful games such as Asheron’s Call 1 and 2, Star Trek Online and other successful Massively Multiplayer Online Games.
I like smaller groups myself, and think 4-5 maximum per team is good enough. It also ease the reading of on-screen action, and GUI managment for healers mostly, but not only.
As for group of groups, i think Rift did that for world events, and Warhammer online too (not sure, my souvenir is vague about it).
I like mentorship. Higher levels can support lower ones, but also lower levels can join higher levels for adventure. City of Heroes did a great job for finding group, joining, having purpose, and it was actually my favorite MMOG for group content. We even ended forming a guild from grouping often with the same "random" players, and we played together several months like so. Dah, i miss this time...
