Yeah, but for every Kane and Lynch there's a CivCity or a PB Winterbottom or a Super Meat Boy or a Flight Control--genuinely good games which sell for very small amounts and attract wide, happy audiences because of this. My hit : miss ratio on blind-buying unknown stuff for cheap has been very good.
If anything, the people who stick to the 5 retail releases they absolutely want are the ones who complain about how "shitty" the sales are. I guarantee you that there will be people this year who complain because they wanted Skyrim for $15-20 and Batman for $5-7.50 and they ignored all the wonderful high quality independent stuff out there. Their loss.
