Dwilight can also be a cold shower for some, particularly those who come in with 'silly' names and expect a lighthearted game... I'm gonna guess and say that SMA has driven quite a few newbies away already.
The island description for Dwilight does mention SMA, and provides a link to the wiki SMA page. Anyone who bothers to read should see that, and know at least a bit of what they're getting into.
