Saints Row IV might not be the most difficult game out there, but by god it's fun. Probably one of the finest sandbox games out there just for sheer insanity, Saints Row IV might just be the best game in the series (although I kind of swing between this and SR2 on a daily basis). You can grab it for around £4 at German site Games Planet, though only buy if you're based in the EU as the Steam code is region locked.
Be quick, mind, as there are only 12 and a half hours left to go for this flash deal.
