Many years ago i checked to see how JADE was doing, saw it was still early in development, so i thought now in 2012 it would be finished. And then i see this, he paused development on ADOM 2 to work on ... this? Some sort of bug fix remake? Why oh why is he doing that, ADOM is just fine it's bugs were minor i played the game a lot and don't remember any game shattering bugs.
It isn't so much a remake as an overhaul and picking up where things left off.
He didn't work at all continuously on JADE since back then.....life/work/marriage/doctorate/etc intervened heavily and much was planning in his head or hacked out into a not-workable form IIRC, hence the situation where it has gone from ADOM being done in hastily hacked together C to ADOM II now being based rather entirely on Java 7. There isn't much history-keeping in the RL scene as there should be, so it is common that many folks operate under a skewed sense of how things have went down based on a background of 2nd hand and beyond accounts chattered about or just folks that've been in this scene for so many years that the memories cloud a bit.
ADOM II development isn't paused, the campaign for ADOM launched after he'd finished up the 0.2.x leg of the official roadmap and the initial release of 0.3.x, while a bit delayed due to the simultaneous work of managing this funding drive and this interim ADOM release, is slated to come out in the near future(should be a matters of days/weeks as this junction, not months) with a good assortment of improvements and feature gains as was pretty much planned in the project roadmap spot it occupies.
This partial release here fixes quite a lot of things, with some being game changers in terms of quality of life(all artifacts now generating proper, certain skills actually functional for the first time, and so on), and most others having the game crash less often and certain exploits not working any further so as to reduce the cheesed aspects. Just take a look through the changelog page linked just a post or so ago and you'll probably find some stuff that you can reckon as nice to have going forward to make it a better experience.
