I like the Xbox Live Arcade games. In the case of Alien Rage, it's hard to beat the value. $14.95 is what I paid.....not $60. Plus I started out playing on the "Challenging" difficulty setting, an have not experienced any of the frustration that must come with the harder settings according to all of the reviews I've read.
I don't need new ideas or innovation or brilliant concepts or intriguing story lines....I need an arcade game: Shoot aliens, find audio logs and bonus pick ups and blast the hell out of everything explosive. That is what I figure I should get for my money when buying an arcade game, and in this case.....I'm a satisfied customer.
