Now that this has been dead for several years due to Krome's demise, what does everyone think of it in retrospective? Despite the poor app, overpriced games, bugs, emulation issues, and various other technical issues, I think it ended up being a nice addition to the Xbox 360 for the classic gamer. Wish it had continued, thrived, and seen a lot of improvement since only a fraction of the content they had licensed ever even made its way out.
I ignored the Atari content besides the exclusive release of arcade Food Fight since Atari Anthology runs beautifully on the 360, had superior emulation, and included everything that appeared here. But I happily bought a big chunk of the Konami lineup that saw release here for the first time in arcade form (Including the excellent Juno First which shines here despite some of the audio being off), Thin Ice and Shark! Shark! for the Intellivision, and three of my favorite Activision titles for the 2600.
Missed opportunity for Microsoft. A Virtual Console style service for Xbox Live would've been an excellent addition if handled well. But the $60 I ended up spending on games was money well spent I think despite all the flaws.
