I'm something of a science fiction freak. It's my genre of choice whether we're talking about novels, movies, or video games. Thus, when I encountered Gate 88 I thought I was in heaven.
Gate 88 is a fairly simple top-down realtime strategy game in which the player is represented in the game - by a space ship. As you fly about you can build structures (provided you have sufficient resources) and your goal is to protect your base. You can build factories to produce more resources, research labs to develop new technologies, shipyards which (shock, amazement) produce ships, and various types of turrets to protect your base defenses. The game is designed with a very console-game sensibility in that it is ideally played with a gamepad, and playing with a keyboard will drive you absolutely insane.
