Title says it all really. If you enjoy one or more aspects of the combat to Temple of Elemental Evil, Incursion, or the old Dark Sun games you'd do far worse than to NOT at least try out the demo to this even if ya don't feel a full game purchase right off the bat. Roll 'em up and slay things turn based as a team just like the old days. The game should be pretty stable(by all standards) but definitely report any weirdness encountered.
Who knows...depending on how Phase 4 and such rolls out I could reckon some convincing could be done to consider it showing up on Impulse down the line.
