I also as a PC gamer can not see why they did not implement 2 character slots 3 at max, then thinking about it just like all companies they want you to buy the game multiple times and go broke. 99.9% of games I play you can have more than 1 character and they do not charge you for that. You would think Rockstar would get on board with this just like all other companies. They want this game to succeed then give us at least 2-3 character slots then more people with play. Consoles have it somewhat made since they can sort of do this already.
I can not complain too hard as PC was lucky to get this game at all, but I as many will not pay for the same game twice.
