I'm shocked at the people who say Ryzom has no world, no story, is not immersive, etc. IMO it has a gorgeous and very immersive world, one I always enjoyed observing - a field of luminescent spores rising lazily from the ground...a carnivore hunting and killing a herbivore, then eating from the corpse, then returning to its pack and one of its packmates going to the corpse to eat as well...the sounds of rain and animals and semi-intelligent plants and miscellaneous ambients, not covered by music...the trees swaying subtly in the wind, a simple element that a bunch of games neglect yet it adds so much to the immersion. Ensconced in unique science-fantasy lore set on a living plant-planet, upon which every creature has its place in the ecosystem - no monsters, no undead, no random grossly-deformed humanoids, just animals, with excellent AI that makes them seem to have purposeful lives of their own rather than just standing around waiting to be killed at players' convenience. And the Kitin, giant genocidal insects, but they are considered an NPC race with their own motives and their own reason for existing, even if those motives and reasons are mysterious to the humanoid races. And Ryzom had a REAL story, driven continually by live events that players could affect (proven by the fact that events and situations did turn out differently on different servers). None of that faux-epic static quest nonsense.
