yep its really great and best of all if you can jump into other peoples games or they can come and help you ;-)
I think the game is great both in single and multi but i rpefer single player since it can be a bit annoying if someone is not on your "level" of technology in game and it can be comfusing when someone ahve something you have not unlocked and so on.. But els great we can build together, share resources, and fight sogether ect ect.
I can highly recommend the game its really great.
