Silent Hill 1 + Shattered Memories / Silent Hill 3 = WTF?

[Beanovsky Durst]

After playing Shattered Memories (and the ending!) I really wanted to try out the original Silent Hill... Oh man, what a game. I got the Good+ ending which made me extremely happy but completly left me confused.

Spoiler:

So, in the good+ ending, Harry gets a baby from Cheryl+Alessa, which eventually will become Heather from SH3 (haven't played it... yet). So he survives to get killed on SH3. However, after a quick search in YouTube, SH1's bad ending leaves Harry dead on the crash, giving Shattered Memories sense; but leaving SH3 on a fuckfest of canon... So which one is the "official" one???

And don't you find sad that Harry's fate is an awful death anyway?

Also there's the Cheryl stuff from SM (her alive and grown up), since she's supposed to die in the fight of the Good+ ending right? Damn, my head hurts...
