How about this for a reason...
I started playing over 10 years ago with the 2d client. I was using a 17in Sony Trinitron monitor and everything looked fine, especially for the timeframe.
Later I upgraded to a 19in Viewsonic flat CRT and everything was still fine.
Then I odd-graded (upgraded in technology, downgraded in size) to a 15in LCD screen and things were still ok.
Then I upgraded to a 17in LCD and the 2d client became small. Luckily by that time, the 3d client became very playable and I got used not only to having the proportion of the game window as it used to be, but for a larger resolution setting, but also the expandable containers for storage.
Then I upgraded to a 19in LCD and things were still ok, the 3d client worked well, however the 2d-based environmental graphics were rather pixelated being zoomed in because of how the 3d client kept the game window at an 800x600 resolution equivalent, but it was easier to see that than an 800x600 window in 1280x1024 setting.
Then KR came out... later it would gain compatibility with large resolutions.
Then I upgraded to a 22in widescreen LCD which KR works BEAUTIFULLY on. Not only does the game window size appropriately proportionally, but it does so WITHOUT becoming a pixelated mess, I can store everything nice and organized with grid view, and I have functionality that neither the 3d nor 2d client gave me.
So while I COULD go back to 2d, personally, I feel that I would simply lose too much of my gaming experience in terms of client quality to desire to continue to play UO and enjoy it.
To make a comparative question... what do you think the outcome would be if UOA was completely blocked from working with UO... how many people would quit if they didn't have that program to augment the short-comings of the 2d client?
