I don't know about you but I don't consider Back in Action a bomb. It may not have been as solid as JA2, (which I loved, by the way), but I enjoyed seeing Arulco in a new way and the game was still a good JA game, in my opinion. Besides, those mods fix any issues people might have with it.
I bought BiA on Steam along with all it's DLC for about $7. After 70 hours of play liberating Arulco, and a desire to play the DLC and go through the game again, I'd gladly have spent full price for this unsung gem.
I've already pre-ordered Crossfire on Steam, so you could say there is some interest!
BTW, have you seen the arabian-style dudes with scimitars in the screens? Way cool!
