What about the Nwn expansions? I feel certain they would've sold quite well.
They sold as well as we expected them to, which is why there was a much smaller team working on the NWN expansions than on NWN itself. The main team which worked on NWN was on another full project.
There are more than 4000 playable, community made modules, many with DL counts > 100k. This doesn't include the many PWs and other products made exclusively for DMed sessions.
As someone who made one of those modules I know that modders are usually keen to incorporate any new material included in expansions, thus necessitating any would-be players to also purchase them. Seems to me, then, that SoU and HotU would've performed quite well, certainly better than the 10-20% that you quote.
Modders are great for building a community and giving a game longevity, but the number of people who modded for NWN or who
ever played those mods was only ever a small portion compared to the total that bought NWN (or its expansions). I know it can seem like everyone is involved when you're part of the online community, because that's all you're seeing, but the numbers just don't bear out, sorry.
