Sorry if I am rambling, but the point is, when you agreed to TOS and logged in your very first time, you agreed to pay for a service, which was to give you an MMORPG FF-themed experience. You would borrow a character slot and get to make any character you wanted and do anything you wanted with them. as long as it was within the scope of the game. If you chose not to progress in any of the quests or content. That is your choice, it is optional. Nothing in this game is a requirement unless PROGRESSION is your goal. In which case, select things become optional and the rest are mandatory.

Want a house? Start making gil. Want to make cool music videos? Start clearing content. Want to get married? Find someone who will tolerate you.
Want to get married with more flair? Pay a little more for it.

I do have one small problem with this though: If, SE decides to start selling expanded content on CS like this wedding stuff. What is going to stop them from adding in new things like bigger houses or upgrades for houses, bigger gardens and the like? I already own 4 Retainers while not directly Pay to Win, it does make my life less stressful and gives me more space to farm and horde things for future patches so I can sell for a bunch.

I am not against this decision by SE, but I really hope the content they implement is satisfactory and don't make the player feel as if they are missing out because they didn't buy the expanded version on CS.
