Giants is a very fun game with clearly off-color humor. It does have swearing and strong language in it so be aware.
It is well made and plays from easy levels to levels that will having you playing over again to get through them. If you are looking for a 3rd person (switchable to 1st person) fooling but fun romp this game would make a great choice. It has a nice assortment of weapons and items to play with and the levels have you doing some very different things to succeed.
It is worth giving a go.
