My challenge to you is Lionheart.
If you havent played or finished this game, then by all means do so!. Its a game that just gets better and better right through, and it will keep you in awe of its beautiful graphics.
I liked the joke someone made about Captive though .. hehehe .. I played it for about 6 months solid and i too was trying to finish it back then until i gave up. Little did i realise back then, that it had so many levels. I dont know what Tony Crowther was thinking when making a game that big? .. Same with Liberation.. nice game but too big.
