I hear ya. I was able to replay Panzer Dragoon Orta and Republic Commando. Outstanding!Just what came with it. Microsoft really knocked this one out of the park, even the industrial design is remarkable. It feels really well made, and manages to look imposing and unobtrusive at the same time.
It's a real shame stuff like Dishonored, Jet Set Radio Future and Project Gotham Racing aren't back compatible, but the fact I can get a game from 2002 and play it in really high res and smooth frame rate is incredible. All the fun of a PC, without having to put up with a PC.
Excited to try gunvalkyrie over holiday
