Photopia is an interactive story about Alley. Hailed by many as being a pioneer in text-based adventures, it's also known as one of the best. Although the story is very linear, it is a truly provocative and fascinating one, and masterfully told. Play it through; It's a story you won't soon forget. I recommend using choosing color.

Since it's easy to get stuck, here's a guide that doesn't give too much away as far as the story goes. Still, try to use it as little as possible.

This is a social experiment game, pretty interesting way of communicating a point. I felt sick after getting the "game over", kind of made me realize a few things. It probably won't change your life, but it makes you think. To get the most out of it, follow these steps:

1)Download the game, do not read the comments posted on it.
2)Play the game.
3)Play it again.

Black Shades

Nothing terrificly special, but fun and quite addicting nonetheless. Very basic, fast-paced gameplay.

You are a bodyguard for the President. Use the weapons (or lack of) at your disposal, as well as a time-slowing Matrix-esque reflex ability, to protect the President from assassins. Advance through progressively harder levels and see how long you can survive. (Oh yes, and there's zombies.)

Like I said, it's pretty basic, but it's rewarding when you take out that armed assassin just in the nick of time or throw the president out of harm's way right as a bullet flies by his head.
