Dive! Dive! Dive!
You know, it doesn't take a video console in order to play some games by yourself. It doesn't take a poker deck of cards, either. There are lots of good single-player board games out there. Nemo's War is one of them, and Victory Point Games is looking to revamp and update its look with a second edition that's up on Kickstarter now.
In the game, you take on the role of the titular Captain Nemo (so no, you're out out trying to find Nemo). Explore the depths of the seven seas while avoiding enemy ships of all nations. Search for treasure, but beware of giant squid and other dangers of the deep. This new version of the game has all-new artwork done by Ian O'Toole.
The campaign is already over their funding goal, so it's on to breaking through stretch goals for the next 29 days.
