wolfsrain: SSG is focusing on wargames since Fawkner left. Not sure who's having the rights for the Warlords series. Not the Battlecry ones, but the original TBS series. SSI was bought by Ubi, so some of the IP's should be there. At least the Five Star General should be at Ubi. Not sure about Buck and the D&D titles.
Tarm: Infinite Interactive, Fawkners company did the latest Warlords TBS game but after reading a bit about the company quickly I got confused. Warlords IV was made by Infinite Interactive, published by Ubisoft and Infinite Interactive was bought by Firemint but the info article also say they now are a independent developer. Makes my head hurt...
The D&D titles are probably the hardest to get considering the D&D licensing problems.
Warhammer is also probably a very distant dream. GW have always ignored their older or not very successful titles unfortunately.
Edit: But Christmas is for wishing and that is what I'll do! ;)
...then let us all descend down upon Infinite and SSG, to get them to release ALL THE WARLORDS GOODNESS! ALL OF DEM!
