as for Horizon Zero Dawn....I'll post some screenshots I took myself (or I'll try to anyways). It really is VERY purty. Took these using the game's photo mode.
so I played several of the SNES Mini games and it works wonderfully. Zelda: A link to the past, Super Castlevania 4, Super Mario Kart, Super Contra 3 and Super Mario World are the ones I tried and they were as much fun as ever. You can save your progress whenever you want to, there are 4 slots for each game and there's also a rewind function that allows you to rewind your game for 30 seconds to undo any silly mistakes., the only trouble is that you have to get up every time and push the reset button on the mini console to do all that. But that's only a minor issue and hardcore gamers won't want to use the rewind function much anyways, if at all.
The SNES Mini controller's cord is supposedly longer than the NES mini controller's cord but it's still too short and you still have to sit relatively close to your TV...UNLESS you buy an extension cord for 10 bucks/Euros. And I'm happy to report that all NES mini controller cord extensions work with the SNES mini as well. I got one and it works just fine.
All in all I'm very pleased with this console. Yes, I wish the console's collection of games weren't limited to 21 games and 99 Euros/bucks is quite a lot of dough for such old games. BUT it's worth it for the HDMI support alone. Mario Kart of course can look quite rough on an HD screen but I don't wanna know what it would look like without HDMI support. And since the console includes real classics (for the most part) there really isn't much one could complain about.
