Giants is one of those games that no one really played, got great reviews and went on to become an obscure title that didn't get the love it really deserved.
Giants is a massive game, with three races, each with their distinct playstyle. With large environments that really make flying around a thrill, it makes the game is a great package.
Well worth the buy to own a class, damn funny game that will sure to keep you laughing right to the end.
