Dead Space and DiRT are ready to download now through Games on Demand. Hmmm, maybe we should try a new formatting for these posts: Dead Space through Games on Demand is $20. Meanwhile, used from GameStop it's $18. DiRT through Games on Demand is $30. Meanwhile, used from GameStop it's $18. Currently, neither is available through GameFly's store. Dead Space is also priced £19.99 ($32.75 USD) in the UK through Games on Demand, while it's only £14.99 new and £9.99 used at retail. That ain't right.
