Anyone else played this N64, Japanese-only classic? If not, do so. Now.
Don't worry about not being able to read it. Though the subtitles are in Japanese, all the characters speak English. XD
But really, I can't believe how awesome this game is (and I'm curious as to why it never came over here...).
There's only three main levels, but the action is so pumped and amazing you might want to play through them again just for the stuff in it.
Stuff like flying around battleships (sideways and upsidedown even) as you shot up everything in sight, blowing away hordes of Ruffians (the monsters) on a subway train, chasing a massive spider creature as it runs around a convenience store (odd, yes, but cool), and best of all:
[SPOILER]
...a boss battle with a massive mimicry of earth. Yes, you fight a freakin' PLANET.
[/SPOILER]
While the controls are a bit tricky (analog for shooting and c-stick for movement, which is a little tough on keyboards), it's still well worth playing through.
(I do have one problem, though: when I play it it keeps blacking out on odd moments. Usually just parts of cutscenes, though. Guess it's something to do with my ROM copy...)
