Finally, I completed the regular game. The final boss would probably be difficult without a rocket launcher. To my surprise, I get more content? Apparently, I can play as Ada now. Hmmm...
Anyway, after experiencing the full game, I understand why it was rated a 10 or close to it from game reviewers. I did find myself just wanting to get it over with after a point, but I couldn't give up. Maybe I will be motivated enough to play the Ada side game.
I give it a 9.9 because it is an excellent game, but I would not purchase a Gamecube just to play it.
Hey Capcom, "See you next!"
