I played UO from beta up to the time around OSI disappeared and EA games took over, even then I played a bit then and there but not near as much.
Anyways for anyone that did and old school UO fan / programmer is releasing a osi replica of UO:R for anyone who might be intersted to play UO back in it's golden days.
And of course it's F2P. http://www.uoforever.com/
