Just wondering what the fourth slot is for? I'm guessing it's either for an online character or a hidden character or it just remains empty?
My internet has been down for a while so I can't check it out when I'm actually playing but if it is for your online character is it to transfer to online play or some way of playing your custom character in single player which I think would be kind of cool.
Also are there any shared properties? I noticed a helipad a marina and a hanger for sale that all my gys can buy but don't want to buy it now on one guy if it means the other two then won't get to use it if that's the case I'd rather wait until I'm done with the main story and know for sure who I'll be using the most.
Lastly so far all the businesses I've bought could only be bought with one guy is that the case for all of them or are there some where you get to choose who owns it and therefore gets the benefits from it?
