Last night and this morning, I did something I haven't done in a very long time - I got totally immersed in a video game.  Four hours flew by and I didn't even realize it.  The game in question is called A Dark Room.  I have been playing it on my iPhone, but you can play it in a web browser, too.  It's $.99 if you want the iPhone version but it's free on the web.  The thing is, there's absolutely no graphics; just fancy text.  But it's captivating.  It's a kind of survival game, but with a subtle horror element that I don't really want to ruin.  You'll have to just try it.  It's a model of game design; everything is tightly and carefully crafted.  It's not terribly hard, but it will encourage you to keep coming back and trying again.  I love the way the story unfolds as a consequence of your actions.  The understated story really is well served by the game mechanics and the lack of graphics.  It's kind of one of those "the thing you can't see is scarier than the thing you can" deals.  

It inspires me to make my own games, especially because it's so powerful without the use of complex art (which is typically the thing I suck the most at).

Give it a try, and you'll see what I mean.
