Do American PlayStation 2 games work in Germany?  I have read of NTSC,
PAL, and SECAM standards and I was wondering if I could bring a game
over and play it on a german playstation 2.

This newsgroup post may be of interest:

"US PS2 games will work on a US PS2, and require a NTSC TV (standard
used in the US and Japan.)

TVs in Europe mostly use PAL.  You'll need a TV that can display NTSC,
or some sort of converter.

US PS2 games will only play on a US PS2.  They will not play (at all)
on Japanese or European PS2s.  Likewise for European and Japanese PS2
games - they won't play on 'foreign' hardware."
