I've rarely ever had more than two alts under construction at any one time, so honestly the only mechanical difference between me playing now versus me playing a month ago is that everything gets recorded, via demo and via fraps, for the archive. Well, that and I lead more trials personally, since many of Liberty's established trial leaders got all depressed and mopey.
The game itself isn't less fun because of the grim news. Assuming it ends on schedule, I'm determined to make the most of what remains. If City finds a way to continue after the NCSoft closure, then I get to keep playing AND I have a vast archive of footage. Win-win.
