It is amazing fun (but there's no language option which is annoying coz both of my neo geo systems are Japanese), and I'm not too much of a puzzle game fan. Its really original and has deep game play (the ghost heads don't appear in random sequences much of the time - there are set patterns to the way these come down), too deep in my case. Anyway, the only thing I have ever enjoyed in video gaming terms are fighting games - reason for which neo geo is ichi ban with me.
I got it coz I was curious - I''m not anymore. Played, loved it, time to move on. If you like puzzle games this is one of the best you are going to play, probably ever. If you don't enjoy puzzle games, its atleast going to perplex you as to why this was never released in no shape or form.
But I'm of a mind that if this game where to be dumped it would be alright as all neo geo enthusiasts should get the opportunity to play it. Money has never been a real issue with neo geo collectors - games have retained their price even though emulation has made even the hardest to get games, available for everyone. This will not be the case with Ghostlop - it will certainly fall in price, but as I have said, money has never been an issue (even less if your dealing with unoficial software such as this - you know the risks).
There is no such thing as the neo geo elite. Just hardcore fans.
There's also a whole world out there, and its just not worth obsessing too much over these things. 'nuff said.
