I'm not up to speed on the new stuff but I have a few predictions and maybe some of you can tell me if I am right or wrong.

What will be valuable:
-unopened first print Amiibos
-limited edition games
-Limited Run games
- Switch games
Can't think of much else

What won't be valuable:
- Xbox One games
- Many PS4 games
-any online only game
- the cash grab "mini" consoles they're making
- all the clone consoles except maybe the AVS

Are these games still going to be playable in the future? What if 20 years from now, you're required to update the games to play them, but the servers are long gone that you'd normally connect to for Xbox one and PS4? They will become conversation pieces, nothing more

I see most of what is being made today as being obsolete in 10 years. We can still play Atari 2600 carts because they were so accessible but the same can't be said for new games
