It’s Halloween Weekend, which of course means, lots of sales. In the Downloads space, because a lot of hidden object games are spooky in theme, a lot of HOGs are on sale.
There is a 50% HOGs Halloween Sale at Wild Tangent; a Halloween Spook-tacular $4.99 sale at GameHouse; iPlay has a new play section where you can play a variety of older games for free; OnLive (cloud gaming) has a free Halloween Weekend Special going; and GamersGate has over 20 scary games on sale as well.
But alas, there are site wide sales as well. All standard games are $4.99 at Big Fish Games (Coupon Code:SPOOKY) and $2.99 for first time customers (Coupon Code: NEW299).
