Just Making Sure I Don't Go a Whole Week without Posting

So...  I guess I ought to write about something.

I know!  Triplanetary!

     Triplanetary is really old board game.  The rules can be found here.  It is played on a map with hexagonal tiles.  The interesting thing about this game is the gravity tiles and movement system.  In other games, ships enter orbit usually by flying into a planet.  In this game, the ships must first slow to orbital speed, then adjust trajectory in order to hit gravity tiles just right.  It will be easy to understand when I explain the rules of movement, as I am about to do.  In fact, that is probably what I ought to have done first.
     Ships have a limited amount of fuel and a limited amount of fuel able to be used each turn.  A ship may use a unit of fuel to alter its trajectory by one hex.  Refer to the rules for pictures.  So, a ship that can use two fuel units per turn may accelerate or decelerate by two hexes per turn, with no maximum speed (except that determined by the amount of fuel it has).  To alter a trajectory, one first pinpoints the hex a ship would land on without any interference from the thrusters (a ship will continue to move at the same velocity as it did the last turn if left alone; there is no friction in space).  Then, one changes that end point the same number of hexes as units of fuel used.  The manual has pictures and is more clear.
     So, gravity tiles are tiles with arrows pointing towards the center of gravity.  A gravity tile accelerates a ship one tile in the direction of the arrow the turn after the tile is entered.  Again, the manual has pretty pictures that are easy to understand.  Using this, one can enter orbit, or use it to change direction or as a slingshot.

     I really like this game, since it happens in space and I have a fondness for space, but it needs more special ships and buildings, which I plan on adding.
