It's Christmas soon, so we'll all be nursing sore wallets as we stare longingly at that brand-new copy of AC: Brotherhood or Black Ops. However, we recently received news from Green Man Gaming that they will be allowing customers to purchase a variety of games for the weekend, which you can then trade in on the coming Monday and receive all but a pound of your money back. Basically, it's the cheapest rental service around, eclipsing even LoveFilm's generous £10 a month offer. Games include Tropico 3, Cities XL 2011, Spellforce 2 Gold Edition, Kings Bounty The Legend and The Void. You can count on us to keep an eye on GMG over the weekend to give you the heads-up on their best deals.
