good point there, but still i would like to use it for survival mode too and i don't play in creative mode well.
I have to agree with Steamburn, creative mode just doesn't have the same feel to it since you can no longer gather block and stuff, the trainer help for people who want for example the full survival experience minus the being blown up all the time, etc.
if an upgrade doens't happen to bad but no harm in asking I suppose.
