Still, that's exactly what appears to be on show in this first trailer for Doctor Who: The Eternity Clock. The gameplay looks a lot like Ubisoft's recent TinTin movie tie-in, if you're familiar with that. We actually quite liked that game so, consider our expectations for The Eternity Clock raised.
The trailer includes a rough release window (March 2012 in case you're curious) for which to tentatively plot on your Karen Gillan calendar. (Yeah, don't try and deny it.) Catch the trailer after the break.
