Indeed, you don't even need €50 for the pack; you can get it for ~€45. Of course, if you still don't want to pay that amount, you can wait some more, but don't hold your breath, as I don't see much chance for such a promo happening in the near future. Truth be told, I think even they can't. The publisher needs to approve of a promo of their games, and I guess not even the GOG staff knows when they can expect such an approval from Atari/Hasbro.

It depends on the module. There are action oriented modules, some other are more traditional. If you search for modules in NWVault, you can specify them to be heavy on roleplay or hack & slash. But really, if you want a true D&D traditional feel, try multiplayer with a friend or two, you won't be disappointed.

Yes, this.

Some engine limitations more or less limit your options for party adventuring in Neverwinter Nights, but there are a few good mods that will set you up. I know what I'm about to type may get me some hate, but...
Neverwinter Nights 2, with the MotB expansion pack, may be the best party-based D&D PC game since Planescape: Torment. The writing is great, the setting is truly fantastic (as in high fantasy), and the expansion pack does away with an almost insurmountable enjoyment-killing obstacle which is the scaling of the lousy engine for plain NWN2. If your big complaint about NWN was the single character plus dammitDeekinwhyareyoudeadAGAIN AI, you may find NWN2 to be a bit more to your liking. And if you get the Storms of Zehir expansion, you get an even more strategic and tabletop feeling game. I don't know if they'll be soon coming to GOG, but you can get the whole shebang pretty cheap ($30?). I know this is totally separate from your original question. Sorry :/

i'm playing through NWN2 right now, got the platinum edition on steam when it was on sale

$20 US standard price on Steam.

Daggerfall's playable landmass has about the same square mileage as all of England. This is why nobody ever walks anywhere. Fast travel is mandatory. Apart from the actual physical size though, it's not really a huge game from the perspective of a single playthrough, unless you're totally obsessed with clearing every single mating-octopus-dungeon in every single province.

While Arena uses "all of the continent" it's not actually as large as Daggerfall is. And while Morrowind *feels* huge, it doesn't actually take that long to walk from one end of Vvardenfell to the other. I'm not sure how Oblivion compares in size to Morrowind, but not having cliff racers certainly makes it feel more hospitable.

All of that aside, BG2 is huge in terms of actual gameplay hours, and in replayability. You could easily spend a year or two playing that game alone. Lots of folks have spent thousands of hours playing it.

Would now be a good time to point out that I got the Ultimate D&D Collection for £13? :D

In fact, with a little time spent enchanting, you can gear up and *jump* across the entire continent (island) in one leap.

Give you some time to enjoy the moon and the pretty night horizon as you sail through the sky after clearing the clouds >.>
