In a startling development, CCP has just announced that in a yet to be announced patch, a feature that will let users customize the exterior of their ships will be added to the game. Basically, we're talking about custom paint jobs for ships here folks! Take a look at this following Kestrel in all its beauty!
Ok, so this isn't exactly true. But you've got to admit this is one feature that a lot of you, including yours truly, would love to have added to the game. Maybe not to the extant of the ship above, but you get my point. I mean corp and alliance logos on ships would be a good start, then maybe color schemes. All of these could be done within certain boundaries or color pallets for each race.
Now, I'm no hardware-bandwidth-tech-whatchamacalit-guy, but I figure that one of the reasons this hasn't been implemented yet has to do with the quantity of new data that would need to be networked if every ship flying nearby would have one of those custom paint jobs. Still, I look forward to the day when the hardware/network/client can handle this and we can start to customize our ships. Until then, we can only dream of Hello Kitty Krestels.
