Will it run? Probably. Blizzard aren’t stupid enough for “it’s specifically designed to only run on high-end machines” which immortal comment I saw on the technical forum of one fairly recent release. Hahaha – way to go!
On the Wurm front, things are happening to the website – I think its down just now, not been to check – but there’s some interesting stuff about it on Rolf’s blog and going on past experience things are being done.
