Flash Game: MotherLoad

Warning! If you find yourself hopelessly addicted to great web games sometimes, then you should steer clear of this game immediately! Wow, the room really cleared out there. Well, for those of you still hanging around, this is a game that is simply quite addictive. All you do is pilot a tiny driller down into tunnels under the surface of Mars, bring back the minerals you collect, cash them in, and upgrade your driller (plus get fuel). It seems quite monotonous, but in fact its not only fun, it sucks you in to go drill down deeper and get more lucrative minerals to harvest. This is a shinging example of gameplay over graphics.
