So I obviously will set up Plex and other apps for watching media, but I want to use it for more. I don't have a pc but if I get a steam account can I stream games to it, also, where can I find a guide to installing a retro arcade emulator so I can play some 16bit games on this thing? Thanks in advance for your help!
You use the supplied shield controller (or equivalent), install the app (type SNES on the store), load your ROMs and start playing.
+1 right now I've spended few hours with Shield TV
RetroArch supports most of old consoles, tested today NES roms with Nestopia core and PSX games (Tekken 3 and Medievil) with PSX reARMed core and it runs very well!
for media try TerrariumTV Baltan Mod (links you can find on /r/TerrariumTV) or KODI
Smart YouTube TV if you looking for YouTube with adblock.
If you want to emulate classic 8/16-bit games then install RetroArch. It can emulate every classic console in one and its completely free (it's based off of Libretro, same system RetroPie uses). I have NES, SNES, Genesis, GBA, and Arcade (Mame and FBA) on mine.
SuperRetro16 for SNES games ($4) - Retro8 for NES ($2)
The difference between these paid emulators and Retroarch (which is free) is the hours you wont have to spend getting it to work.
Now you just have to wait to unwrap it ;-)
I haven't used them, but for OTA whole home DVR consider an antenna, HDHomeRun Extend, and Channels .
Plug it in and use it. I don't know what else to tell you other than Google will lead you to a lot of information on the internet.
If you've got decent Internet and are reasonably close to one of NVidia's data centers, GeForce Now is certainly worth the price of entry. Not sure I'd spend much money on Steam games with zero insight into their pricing once they start charging again, though. At least not without a PC you can play them on/stream them from, anyway.
If they revert to the $8ish a month for unlimited play, I'd be happy to start paying them again, but there's a decent chance there will eventually be a fixed number of hours included given their experimentation on the PC side.
Wrap it and wait
Suggest you search this forum this question has being ask before and people listed what apps they have install. YouTube has a ton of videos how to set up Nvidia Shield.
