Rio Grande Games has teamed up with Donald X. Vaccarino (Dominion, Kingdom Builder) yet again, this time for the time-travel board game Temporum.
 
In Temporum, players assume the role of time travellers, manipulating both subtle and major events in history in a bid to gain the most power at the moment that time travel is invented.  The game board shows different "paths" that history can take, and players use their hand of cards to travel through time and alter this course of events.  Two to five can play, and each game lasts between 30 and 60 minutes.
 
Temporum is expected to release later this year.  It will have an MSRP of $49.95.
