I so totally agree man... Wouldn't it be cool to meet up and have a GT Racing Feast all day. We could all bring along our consoles, i-link, memory cards, games and stuff it would be great.
If it does exist already, I wonder where.
There's some legal hitch to these things though - Copyright, displaying in public places etc ...
I reckon Japan will have venues every week...
I'm in the UK so I wouldn't be able to join you without spending a lot of cash..
