There's already GemRB, so why I shoud buy this version?
Does it uses FHS correct folders or is it installed in '/opt' as many other games that don't support it?
One advantage for GemRB is that you can build it from source and make changes that you need.
I am hoping Gemrb will be able to use the new content.
I guess it shouldn't be much harder for gemrb to run Baldur's Gate 1 EE than Baldur's Gate Trilogy mod .... I still prefer BGT with other mods, though.
