The Guild of Good Games will be launching a KS campaign for a game tied in to the LARP world of Empire (?), Runes Way. It's actually a system rather than a game.
There is a dedicated solo/co-op mode, The Paragon's Path, and you can also play it as a puzzle.
Last, you can also use the runes for divination by laying them into a seven-hexes hexagonal structure named the "Wheel of Meaning".
