Well I believe the world won't end there but at some point past 2015 (if we don't change what we're doing to the environment) the world could stop life but then past 2300 or something life could begin again.
Well I found out about KH first back when COM came out, I was going to rent it because the song in the commercial was great. But I didn't get a chance.
Then when all my friends were playing COM and KH2 they got me into it and I loved it and played all the games in order.
