You get a lot of information about Sin and Punishment: Successor of the Skies from its title. It will punish you. A lot. The Successor of the Skies bit, though… ignore that. That makes no sense.
It punishes you because it's a Treasure game. Treasure, as all proper hardcore gamers know, is the cult Japanese developer behind arcade shooter classics Gunstar Heroes, Ikaruga and Radiant Silvergun, a game so rare Kensington and Chelsea estate agents accept it in exchange for two bedroom flats. Probably.
On-rails shooter Sin and Punishment: Successor of the Skies isn't as punishing as previous Treasure titles, but it'll still grab you by the scruff of your neck and head butt your nose into your brain with each increasingly difficult, and barmy, stage. And that's just on normal.
But, and this is the crux, it's huge fun, immensely satisfying and one of those games that, when you get good at it, transports you into the mysterious place known only as "The Zone".
"The Zone" is a weird alternate reality/dimension/black hole/Zen state of being/Nirvana place thing where gamers separate mind from body and achieve remarkable feats of video game wizardry. Brow furrowed in concentration, you stop trying to beat games and just beat them, a bit like Neo fighting Morpheus in The Matrix, except with more pew pew and less kung-fu.
Sin and Punishment transports you into "The Zone" for about five hours, give or take skill level and the difficulty you're playing it on. And while those five hours last, you'll want for nothing else.
The obvious reference point is Successor of the Skies' predecessor, 2000 N64 title Successor of the Earth, which you've probably never heard of because it was only released in Japan. A more Western-friendly comparison is ancient arcade shooter Space Harrier. You control a small boy who can fire an endless stream of bullets from his arm and fly about with a jet pack. You shoot into the background, aiming the on-screen pointer with the Wii Remote and dart about with the Nunchuck thumb stick. A quick evade, which makes you temporarily invulnerable, helps you dodge the millions and millions of enemy bullets, a sword slash reflects enemy fire for mega damage, and holding down the shoot button charges a powerful blast, which you can release for mega mega damage.
The game's control scheme is one of the best fits for the Wii I've ever seen. Moving the pointer with the Wii Remote is accurate, intuitive and perfectly in keeping with the 'aiming a gun and shooting at lots of enemies' premise of the game. This is one of those rare occasions where using two thumb sticks - one for movement and one for moving the targeting reticule - is worse than using the Wii Remote/Nunchuck combo. I know because I've tried to play Sin and Punishment with the Wii Classic Controller. It's balls.
