February's been an interestingly finance-based month for free games. Two of the five picks below involve some sort of economical consideration as their core mechanics - though, in fact, they could hardly be more different. Where one revels in silliness and invites you to try to make a million dollars, the other attempts to show us how easy it is to lose everything and become homeless. A bit like being a games journalist, then. Which is interesting, as there's a game about that, too. Read on for our February picks.
