Yes!! I love this series, MR2 was the best monster rancher ever made. I remember playing hundreds of hours, raising my Big Blue (Golem+Tiger) or my Pixie+Golem.
And I remember putting the metal gear solid disc and having a special monster (gaboo i think?) it was like a jelly with a bandana.
I need to play that game ASAP
