HH is a visually nice game but gameplay doesn't match the looks.
EM's:
El Dorado
Surf Champ
SS
Sinbad - ridiculously simple, very addictive!
Devils Dare - mine is broken at present but a good game when it was going
Spirit - never played one but now own one overseas - need to get it shipped home
Black Hole - Own one but have only played it 5 times - (lack of time)
