Again, though, I'm mostly seeing consoles in this list. With the reasoning being that there is little backward compatibility between console generations.
Depends on the system. The PS3 is backwards compatible with PS2 games and a lot of these HD remakes are of games that were on PS2.
There aren't a whole lot of PC games getting this treatment. And that is what most people on Blues want. Serious Sam aside, of course.
I agree. I would like to see more classic PC games get this treatment. Given the popularity of remakes on consoles, I wouldn't be surprised to see PC games start getting the same treatment on a more regular basis. Publishers recognize the value of nostalgia, which is why they're still using IP like X-COM and Duke Nukem.
