I will always maintain that backwards compatibility means putting my previous gen disk in the drive and being able to play it.
It's not TRUE BC if it's just streaming or some digital download from an extremely limited selection of a previous console's games. It's just fake BC at that point. There needs to be a new term made up for this streaming/digital download form of what they're calling BC.
Kinda like how my TV "says" it has HDR, but it doesn't have a full color gamut, so it can't possibly be real HDR, it's fake HDR (or as I like to call it pHakeDR), it just accepts HDR content.
Or like how games call themselves "full game" when there is tons of DLC locked behind a paywall. Let's take DOA5 as a great example, they will call it the full game, but it literally has hundreds of dollars of DLC that's not included and you have to buy separately to truly have the "full game". When any game has DLC, and it's not just included with the purchase of the "full game" automatically, they shouldn't be able to call it a "full game", it should be called the "base game".
There are a few other things like that I could mention, but I'm starting to get a little off-topic, so I'll stop.
These things really are a pet peeve of mine though. It burns my ass how companies continue to obscure terms that should have one meaning, but now means anything they decide to make it mean. And it also irritates me to know that this sort of thing will only continue.
I'll stop ranting now.
