You could be right about Beatmania! I think those type of games are a bit crap anyway! Most of the best games on the Amiga were not original anyway, I don't think - shmups for example! The last great creative period in gaming, in my incredibly humble opinion was during the reign of the Speccy and C64.
Truely new concepts were few on the Amiga and a lot of the original games that come from Japan are just too strange! Although I definitely agree what you said about the Americans.
I agree with Shatterhand too! This can be said about life as well. Everyone must of heard older people say that 'it was so much better in my day'!
God, it's sounding like a sociology discussion now!
