There is a way to change the rules of the space station before going there, I believe theres someone playing space rules at the launch site and a estharian in disc 2 (I believe it's during the end of disc 2 in G-Garden all I definitely remember is the other region is Gabaldia rules) which means if you spread rules you want to Gabaldia playing the estharian there will let you change esthar's rules. This isn't always easy but the best thing to do is save when you've got Gabaldian rules and if an unfavourable action occurs after the card game with the estharian reset the game, the rules changes are random. Once Esthar's rules are changed you can before going to space change space's rules using estharian rules as the change rules. Space is so much easier without random and other horrible rules too!
