Yes, well, I wouldn't recommend those myself. If I want to play BG or IWD, I'll actually go play those games, not mods that try to convert them to a completely different ruleset.

The problem is that both of those games use 2nd edition rules, while NWN 2 uses 3.5 rules, which are completely different and I just don't see how they can hope to both be relatively faithful to the original games and keep them balanced.
