Summary: Space Invaders, if you don't know it, chances are good you're not a gamer. This version does an excellent job of making the game fun and relevant to more modern sensibilities. Fast-paced, with balanced power ups and variable difficulty, just turn of the silly motion backgrounds. Pick this up if you have a PSP lying around!
Summary: Its one of those games that when you die you say "well let me play just one more game" and before you know it its time to get up and go to work. Its not an "emulator", they actually re-made it, with colorful backgrounds, cool sound effects, and killer addiction. Its simple and easy to pick up and play, perfect for casual gamers who just want to shoot aliens for a while.
Summary: Space Invaders Extreme is a must buy for arcade fans, old school gamers, or just old gamers. It will challenge even veteran gamers on their reflexes and tactics to approaching which powerups to get, and how to survive. I am a hardcore gamer, and when I heard about this game I dismissed it simply as "another remake" but after researching it, and actually buying it, I stand corrected.
Pros: A fantastic remake of an old classic, and at only 20 bucks. The integration of visual and musical style is exceptionally impressive. You have to play it to understand what I mean, but, really, this game just really over delivers on all fronts. It was far more than what I expected when I purchased it.
