I got into Gears with Gears 3 and then went back and played 1 and 2. Mark and I played hoard mode in 3 a lot.
I guess I'm thinking about works of art that have lasted for hundreds of years, even thousands. Is Gears going to be playable in 2600? Not that I'm going to know about it.
For Xbox One yes, and I'm considering it. Xbox 360, I think so, but I never tried it. I know you can store games there but I'm not sure about running them from the external hard drive. I would assume so, but I haven't tried it.
