I was Wondering, I have just finished playing my first Team game and was Wondering if Metal and Energy are shared with armys and players on the same team games.
Team games, not as far as I'm aware. On the other hand, if you're talking about shared army games, then yes, economy is shared. Later on you may be able to mix those kind of things.
It will be optional in the final game. I'd imagine there'd be options, besides 'being in the same team and that's it', such as: Share units / buildings? Share economy? Able to donate resources? Able to donate units? But I don't work for Uber.
