It's a relatively slow weekend for game deals, but there are at least a couple noteworthy bargains. Microsoft's Games for Windows Live service has cut 75% off Borderlands, putting it at only $7.49 -- about the cheapest we've seen. Meanwhile, both Steam and Direct2Drive have reduced the Serious Sam titles by a substantial amount. GOG doesn't appear to have any actual discounts, but it's worth noting that the service has relaunched with its new design and offerings including Baldur's Gate.
