This is a topic I've been giving some consideration to for the last little while. in a lot of MMOs (and even some other games) there are special objectives you can achieve at endgame for a bragging rights reward - the Mind's Eye piercings in Monster Hunter, Legendary/Relic weapons in a number of MMOs, Special armor you can only craft after going through hell and back, and other such things. The important thing with all of these is that they're always long-term grinds that are intended to take the better part of a year. These are all extremely interesting because whenever they're patched in, they become something the top-end players of the game start pursuing, and even among casual players, getting them is something of a fun trip that gives them a reason to log in day after day to get that little bit of extra progress done.
I'm of the opinion that adding something like this to City of Titans (perhaps not at launch, but eventually) would be very helpful for the longevity of the game. Certainly, we're all interested in the mechanics of the game itself, but having something to work for is a big part of what keeps people invested in MMOs, which in turn gets them coming back and spending time in the game, which turns it into recurring spending. It's not vicious if they're actually getting something out of it, and a bragging-rights reward is exactly the sort of thing that adds to a game without causing undue problems for specific players.
With City of Titans not being gear based, it's at once both more and less restricted; there's no predefined thing we can slot it into (such as a weapon, or armor, or something like that) which makes the decision on what it can be more difficult. With the costume creator being such a huge deal, though, I could easily see it being something to do with that - maybe a cape that flows with a starry pattern to it? Some kind of extremely impressive aura, or a trail in their travel power? It'd certainly fit the style of some superheroes. More directly, part of the benefit of this is that it has no stats. No direct value that gives players an edge over people who haven't completed this "legendary" goal. This is important for balance reasons and the rule of fun - a style reward should JUST be style, in my opinion.
Anyways, this is as much intended to start a discussion on the topic as it is a suggestion for the devs. I'm curious to hear what kind of ideas people would have for this kind of reward; what would you spend months working towards?
An infinite number of tries doesn't mean that any one of those tries will succeed. I could flip an infinite number of pennies an infinite number of times and, barring genuine randomness, they will never come up "Waffles".
