Extraterrestrial Grail is a free, off-line, single-player, turn-based strategy/board game in which you play against 1-3 computer players. Extraterrestrial Grail takes place in outer space in which you are an alien searching for the Grail. Only one player gets the Grail at the beginning of the game, so the other aliens must find out where it is by fighting each other and searching planets for it. The object of the game is to have the Grail card in your hand when time runs out. This video game was inspired by the board game in the book Interstellar Pig, written by William Sleator.

GAHH!My love of board games...It is too strong. Man this game looks good.

Thanks! I love board and card games as well. You should try playing it and let me know what you think! :)
This doesn't look too bad.
I find the interface hard to get around with. It's hard to know whether it's your turn exactly, hard to remember even what your character was, hard to grasp the made-up alien names - and thus hard to get around with. I literally cannot keep them apart.

It's a little bit odd to basically just have the time run out on you.
But it seems that there is more tactical thinking required to distribute the cards properly among players and characters and use them well.
Without some experience I can't think that you will be able to do much with this.

And please, please change the music - it's exhausting .. but hey, you can just turn it off I think.
