I'd hope for:
Icewind Dale 2
and maybe Pool of Radiance 2 (the Atari one)
I like how they had quasi 3rd ed rules which for me are way better than the very limited 2nd ed rules, as I like playing stealthily and allowing melee classes more fun abilities than just "smack! smack!"
Despite the fact that I favour playing wizards I find just mere hit point damage as being all melee characters could do *innately* as incredibly tedious, and so wrong (combat is very fluid, 4th ed over complicated in ways but melee classes should be able to MOVE enemies in combat as it did).
And 1st/2nd ed stealth rules *suck*
Flat percentage, though DMs had optional and very poor rule to adjust for enemy Hit Dice, was just rubbish (and hey I'm a DM and used to adore playing 1st/2nd ed...until their limitations bugged me to hell.)
Also, "feats" and skill sets are vastly better ways to do things than "proficiencies".
and these games would need and deserve major re-workings/improvements IMHO to make them into more modern graphics:
~Eye of the Beholder (which got me into computers, not just "gaming" thanks to my dear old Amiga)
~The Dark Sun games, VERY under appreciated classics, IMHO!
And well of course: Planescape Torment
I'm sure some folks would love to see the eerie Ravenloft games re-done as well
A *PROPER* Neverwinter Nights 3 would rock of course but "sword Coast Legends" will kind of fill that gap a bit?
