While Frank and Ben Kuchera of Ars Technica are rather enamored with Shadowrun on the 360 and the PC, as a game it's a rather hard sell. The price is high for a multiplayer-only title, and of course it requires Vista to run. Same thing with Halo 2 on the PC: it's basically a older Xbox game that requires Vista for absolutely no reason and shows that Live on Windows still has quite a ways to go before it's a killer-app. Clearly these games aren't worth $50 apiece. Luckily, Circuit City has you covered: buy Halo 2 on the PC for $40, get Shadowrun free. It's like only being charged $20 for each game and, if you have Vista, that's a helluva deal.
He is not sure what such an aggressive sale says about the earning potential of these two games, but if you were interested in either of them and were just waiting for the price to come down, today is your lucky day. Sure, they won't throw a copy of Vista in there to sweeten the deal, but it's still an inexpensive way to try out the games and the new Live service for PCs.
