I think some people have not read the post. Either that or they don't get exaggeration, unless someone types "exaggerated." It kinda ticks me off that I can't be sarcastic without typing sarcasm or putting a up. Well, of course, unless I want to get reported because someone thinks I'm being serious, even though my comment is WAY out there. I know this is the internet, but COME ON!
Anyway, I think he brings up a good point. If you can make the games the same on both, fine with me. But if you can't, why punish those on the system that could have had a better version. I think the biggest example of late is FF13. I'm sorry 360 fans, but content was chopped off so the 360 version could be. There were 3 or 4 areas removed so that it all could fit on the 3 discs. I'm not saying that the game will be crappy now, just that extra content is always better, epecailly when it was already running on the PS3 before it was removed.

You claim that FF13 has only 6.8 GB of game data. Now I don't know if it's true, but let's go with that. On the PS3 that's all it will take up, since it's one disc. However for the 360 version you have to take into account how much of that has to be repeated across all discs (of course unless you want to have to switch discs repeatedly because you're in a new area, even if you've been there before), plus code on discs 2 & 3 so that the game can read the info from your HDD so it can load all your from the previous disc (though I doubt this would take up much space). And let's not forget that on each disc MS reserves ~1GB for security purposes. After all this, you can see why they may have needed to remove things from the PS3 version so that both games would be equal.
