you really need to pick up ALIEN HOMINID, MEGA MAN COLLECTION, MEGA MAN X COLLECTION, and METAL SLUG COLLECTION for the gamecube, too. By far my most played games on the system (too bad the Cube never got the Capcom Classics Collections like the PS2 did.. those things are so brilliant, like 52 games!). ALIEN HOMINID is a game I always see at pawn shops for a few bucks, and it's usually on sale at the developer's website for $10. Fun as hell game. And hard. I beat it recently -- no kidding, I had been played it off and on for 3 years and FINALLY beat it about a month ago.
For those who care, it has probably the best 2D animation ever that isn't made by Vanillaware or Capcom. Eye-searingly beautiful. The entire game was created by a team of about 8 people.
AMAZING graphics, fun as hell/hard as hell gameplay, tons of levels, surprisingly violent, tons of weapons that bring to mind Earthworm Jim at times in their insanity, a good sense of humor, you get to ride in helicopters and cars and all kinds of shit.. great music... so so so so well made and imaginative. Highly reccommended. Though I always see it at pawn shops, I just read the game is out of print, and the Gamecube version is considered the definitive version by the developers and it's now out of print too and they're not planning on making anymore. So, it'll probably go up in value a bit -- who knows, it might end up being $20 eventually. Noooooooo!!!!!!!!!!!! I CAN'T BELIEVE they sold this brand new for $10, though. Jesus.
Oh, forgot to mention, the game has a bunch of fun little mini games that are minimal (is that when "mini" stands for? Er.. no.. MINIATURE) but are almost as fun as the game proper.
