Are we excluding the switch?
PlayStation I'm going to get (try) day 1. Four generations have shown they will have games I want to play. Plus I don't want to deal with trying to find one.
If Xbox is still going full PC BC? Then nothing.
If Xbox actually had X series exclusives? Alan wake 2. oh wait.. dark dreams don't die.
Hard choice between those two.
Kind of hard to preorder a Switch since it's been out for several years ago. However if you had asked me 4 years ago I would have said this,
"The only console I've ever bought at launch was a SNES. However, what I've wanted from Nintendo for a long time is a Zelda game that gave me the same feeling I had with the original. Give me the freedom to explore and go wherever I want. I don't care if I go somewhere hard that will kill me. Let me do it! Make Zelda a game about freedom again. If they do that I'll preorder a system, even though I never buy them at launch anymore."
Of course, this is exactly what they did, and so I preordered a system.
I really believe that games sell a system more than anything. A company can charge whatever they want as long as their games are good enough. However if they are going to launch at a high price, then they better have some phenomenal games. Is their system powerful? Well they better have some mind blowing games to show off that power. If it's just the same type of games as before with better graphics, then that doesn't really justify the price, IMO.
