I don't know how Aion works, but if there is a bazaar / self-shop system that would totally suck.
A lot of people like to set up their shop to sell their goods while they are away doing other things...including sleeping and work/school. In a game where they charged by the hour, no one would ever want to do this.
On the other hand, many people may not be able to play the game for 18 hours a day like some people. Maybe they don't want to pay the same amount that someone who can play all day pays, although I don't see why it really matters.
But if I was in charge, I wouldn't set up a system like this because it might make some people play less.
If you're charging 15$ a month as a base rate, those who play are going to want to play as much as they can to get their money's worth.
But if you charge by the hour, some may play less (only what they feel they need to, to accomplish something) in order to save money.
The only reason I can see for the developers to do this is if they have issues with too many connections to the server and want to limit it.
18$ a month for 8 hours a day? There are a lot of people out there who have the free time to play 18 hours a day if they want. That would be way way too expensive.
In the end it sounds almost like it would follow the same rule as many "F2P" games. The people with the most money in real life will be the better players because they can pay to play 18 hours a day, as apposed to those who can only afford 15$ a month.
I'd rather play a game where it's a standard subscription fee. As long as you can afford that then everyone has an equal opportunity in the game.
I don't see a reason why the wealthy should benefit over the poor.
It just sounds like an item mall to me except it's a play-time mall. The ones with more money to blow benefit more.
I'd rather everyone have the same opportunity when it comes to a subscription MMORPG.
Toasting makes me uncomfortable. But toast I love. Never start the day without a good piece of toast. In fact, let's toast to toast.
