Aisle

Having only just returned to IF after a brief and fruitless attempt at Zork a couple of years ago, Aisle is an excellent welcome. It's not as involved as many other games, but the writing and concept are great, and for a beginner like me it's an excellent counterpoint to the misperception that IF is all about "take sword" and "kill orc". The range of possible actions is also quite a surprise, and kudos to the author for that.
