Italian people say "mai giudicare un libro dalla copertina", in English it sounds like "never give an opinion about a book when you only have seen its cover"... well, there are many games too with nice covers but poor gameplay... I.e. I remember "Soldier 2000"
: a tricky cover with a not so beautiful but charming woman in futuristic assault suite (the charm is made by armor and scars) in a lone swamp. BTW, the game was very poor.
Here's the cover, thanks to Exotica
