The reason why I find this image inspiring is because it represents everything I love about fantasy tabletop roleplaying games and the kind of adventures I like to run. There's a nicely mixed party of warriors and magic users, and they're descending into a dark ancient ruin ready for action.
I love the mood the image creates; there's tension and darkness but the characters are tooled up for adventure. There's a nice nod to the original Dragon Warriors cover image with the skull in the winged helmet in the bottom right - the unfortunate soul - and there's a large clash of cultures; robed sorcerers, an armoured European knight, a powerful Nordic warrior, all descending into what seems to be a tomb built by indigenous South Americans. It's excellent and really helps spark the imagination.
