I figured GBA and PS2 were pretty different. I figured mobile phones and the DS were pretty different. I suppose all they need to do is release the collection via PC. I personally don't prefer to have to install a game on my computer while I still need to use the CD to get the otherwise-worthless files to do anything. I installed MechWarrior on my dad's PC because he likes MechWarrior and I helped my mom repeatedly install search puzzle games on her PC some of which still require the disk to play. I thought I'd try out this game called Paradise since I was able to get it fairly cheap at a used-stuff place. Having to repeatedly exchange CDs for little to no reason...
