this is a collectard topic. who cares how many variants are there. only collectards care about variants. Like you said, play the games.
One version of Champions Forever Boxing will not play correctly under certain console setups. That is a game playing issue.
Encouraging people to collect sealed games, grade them, frame them, hang them on their wall to admire and think about the increasing profit margin on your investments while staring at them until you flip them
for money (not simply "flipping" them to display the backside of the framed sealed game case)... is engaging in collectard enthusiasm.
