Honestly, the apple TV is the least spammy by a long shot. I also hear great things about the Nvidia shield, but it is pretty ancient by now. Or use a computer, but of course that’s got its own annoyances. Of course these are all the most expensive options, apparently for a reason.
Every year I enjoy the hell out of Left 4 Dead 2 around Halloween. If you guys have never played it, oh you’re in for a fun time. Super cheap and runs on a potato at this point if your Xbox brother can find a computer.
