Thanks for your help guys, I'll be downloading this as soon as I get chance (and playing offline! )
Thanks for the info Pyro and thanks to Wraith for the interesting insight into the whole steam/drm thing. I guess I agree about the lack of incentive to innovate or provide value for money on console. A monopoly is never good for consumers. Interesting take on the Steam service. Your post is actually a petty decent advert for the system. I can't see how the service in and of itself is a bad thing or where the real hate comes from. Personally I really dislike the DRM thing but only because it severely limits my access to a wide range of games. I also don't like having choices made for me. However, the opportunities they provide for small, independent developers is great news for everyone. For steam because, as you say, many would be inclined to 'take a punt'on a game they might otherwise ignore, for developers because they have access to a wider audience and a cost effective way of producing and distributing the games they really want to make, and for the consumer because we're getting access to more innovative, original and interesting games, improved choice (beyond just the mainstream 'AAA' titles) and better value for money...
I'll be interested to see too what impact the whole steam box thing has on the gaming market. On the surface of it it seems like it might be a good balance between the benefits of pc gaming and the convenience of a console.
I guess it remains to be seen... in the meantime, I'll be enjoying xenonauts!
