Classics like Baldur's Gate, Planescape: Torment, Icewind Dale and more running on the Infinity Engine should live on forever thanks to open source reimplementations like GemRB.
While we do have the Enhanced Edition for many of them thanks to Beamdog, it's probable that eventually GemRB will be the best way to play all of them as we've seen with other open source reimplementations like OpenMW for Morrowind and OpenXcom for the classic X-COM. GemRB enables people to bring them to new platforms, better modding and continue improving them long into the future.
GemRB v0.9.1 just went up recently and here's what's new:
- Icewind Dale 2 can be progressed to well into chapter 5
- Faster loading and saving, faster OpenGL rendering
- Use magic device skill, precise shot, iwd1 bard song choice
- SDLAudio plugin now supports ambients
- Console history is now preserved, more text colors externalized
- Logging is now done via fmt (bundled headers)
- Python3 support (now the only option)
- Unicode support (iconv not optional any more!)
- Spellcaster ai, effects, scripting, projectiles, weapon style customization
- Audio, drawing, appimage, ini spawns
