It's almost here!

Time to get those Wii Points ready!

Our good friend Tyrone Rodriguez of Nicalis has just informed us that Cave Story will cost 1200 Wii Points when it makes its North American debut on Monday. That means you'd better get those points ready to go and you'll even have enough for a nice Super Nintendo game left over. Not too shabby considering you're getting quite a bit of what was originally going to be downloadable content already built right into the game.
