I bought my friend and I both a copy for Christmas and tested out multiplayer with only the 2 of us. A few issues sprang up. I found we were constantly asking each other how much resources the other had to calculate optimal expenditure on modules since every person has their own resources. A resource hud for every person in game would be nice. Also as far as loot goes trading isn't an option. If my friend picks up something i need i lose resources because he has to sell it through a shop and I have to buy it. I'm not sure splitting the income is a good idea either, because after researching an upgrade the income per person doesn't increase with every upgrade making the research practically useless until its upped a few times.
