Space Invaders Extreme. Put out by Taito to mark the 30th anniversary of the release of the original classic shooter, this re-vamped outing is like the offspring of Rez and the 1978 Taito original.
If you appreciate retro gaming to any degree and own a Nintendo DS or Playstation Portable, just go buy it. Right now. This game is awesome.
And if you’re really hardcore, go grab the Arkanoid DS / Paddle controller bundle. The paddle is fully supported by Space Invaders Extreme.
And if you’re off-the-hook hardcore, well, I guess you need the tattoo.

What’s all that crap in the background of the game? That makes it virtually unplayable for me. It needs to be toned down!
The paddle-controller support is the detail that makes this anniversary version especially interesting: it changes how the player interacts with a familiar shooter, rather than only updating the visuals. The earlier comment about busy backgrounds also raises a useful readability question for remakes. For a different kind of browser break, I develop Dragon Bonding, a free fictional dragon adventure with six short stages and guest play; it is unrelated to Taito or Space Invaders.
