Time are not changing. We had the exact same discussion a few years ago.
Thing is, they are doing what we really want. What do we really want? We want to save the memory of those old gems which, in many aspects, are way better than the new crappy games they dish out regularly now.
By selling the game again, they keep that game alive. It's spirit, it's vision, it's playability, it's greatness.
Mission accomplished. And we'll always be here to watch things run over until they tire of it and stop selling the game again.
