I don't know why the first reviewer said what they did. The 50th anniversary flashback console includes Activision favorites, like Pitfall!, River Raid, Megamania, Spider Fighter, Starmaster, Chopper Command, Kaboom!, Freeway, and others. It also includes iMagic's Demon Attack, Dragonfire, and Moonsweeper. And from Mattel there is Burgertime. Front Line is there from Taito/Coleco. This has 130 games vs the 40 games that the Flashback 2 had, and even the 2 had Pitfall! and River Raid.
The save states are pretty nice. You can save your game at any point and load it back up the next time you play. The joysticks feel very close to the originals. It comes with some tight paddle controllers for some Warlord action. You cannot control the menus with the paddle controllers and they have to be plugged into port 1, which is where the joystick with your menu controls should be plugged in to. It doesn't work as well when plugged into port 2.
The rewind function is interesting, but feels like cheating to me. Made a dumb mistake? You can rewind the game a few seconds and try again. Want that retro scanline feel? You can enable that in the game menu (not the global menu, which is a little weird).
Overall this is a pretty great retro console. I really wish they could get the licensed titles that I miss, like the much hated E.T., Raiders of the Lost Ark, Spiderman, etc. While some of them were panned they were still an important part of my childhood. Unfortunately I am sure Disney and the other movie studios won't re-up the licensing for those IPs.
