here.Even if I were to ignore every other game on that list, I would give the highest of recommendations to
Planescape: Torment. I know I've already said this several times in the past, but it is still to this day my absolute top favorite of the Bioware-style RPGs (even though P:T wasn't actually made by Bioware), and this includes even the more recent similar games like Dragon Age, Mass Effect, Jade Empire, etc.
Baldur's Gate is pretty awesome too, especially when taken as a whole, since you can import your character from BG1 into BG2. (I actually tried playing through this again a few years ago, using the
BG1 Tutu stuff, but didn't get all that far into it. Still want to give that a shot again someday, though.)
I've played the first
Icewind Dale also, but it's like a more combat oriented version of Baldur's Gate (i.e. more fighting, less towns and less NPCs to talk to), so I didn't like it quite as much. Haven't played
Icewind Dale 2, though.
I've played
Neverwinter Nights as well, and I guess it was okay, but the sheer horrible amount of bugs in it at launch* really soured me on the NWN series as a whole. As such, I haven't played any of the expansions for that, even though I bought Diamond a few years ago. No clue if they finally fixed the remaining bugs in that version. I notice NWN2 isn't in the list, but then it doesn't appear to be available on GOG at all.
As for the rest, I haven't even heard of
the other games on the list before, so can't really give a recommendation on those one way or the other. If anyone else has played the others and would like to give a thumbs up/down for them, let me know.
* - A lot of which were still in it even a year or two later when I tried it again, and some of which I actually ended up fixing
myself by exporting the storyline campaign out to the built-in level editor (which included a script editor which was pretty much just a C/C++ API), even though you technically weren't supposed to be able to do that, at least until after you'd completed it once. But I found a way, anyway. Let me just say that having to debug the code on the game you bought just to play it isn't fun, though I suppose that's a bit better than not being able to do anything at all about the bugs. These days, when I run into a bunch of bugs like that in a game, I just stop playing it altogether, at least until they release a patch for it, and sometimes not even then. I guess I just had way more patience back then than I do now for that sort of thing.
