You ask fair questions, but they're clearly loaded. Games are like any other project, and the desired scope for games has gotten enormous. If you don’t like those games there’s more indie and AA titles being released these days than there were AAA titles 25 years ago. An awful lot of that is down to Unity and Unreal.
> does it feel good to walk around in?
This isn’t a priority for every game. A bunch of the most beloved games have absolutely awful movement mechanics. It’s very often a deliberate choice to _not_ make player movement feel like either Titanfall or TLOU (partially because it’s an incredible amount of work to do that). Some really good examples are Witcher 3, RDR2, shadow of the colossus, the entire fromsoft collection. (And notice none of those are Unreal!)
> does it default to having a nauseating motion blur filter
Motion blur is super divisive. Anecdotally what I’ve seen is that most people just don’t care and there’s a very vocal minority who disable it. We had telemetry on a previous game and the number of people who opted out was minuscule. We gave an option for on/off on first launch of the game. It helps when frame rates are teetering on the edge of our budget which is often why we enable it.
> does it run at 40 FPS with minimum graphical settings on a $2000
What games do you have in mind there?
> even just "is this fun? challenging? interesting in any other way?"
This isn’t fair. Any game I’ve worked on has had the majority of the team playing every week, and the gameplay and design teams playing more often than that. You may not like the game, and that’s fine, and some games might be more vanilla than your liking, but those games are wildly popular. Personally - I think the praise Nintendo get for a simple platformer (which has excellent controls, admittedly) is way overblown, and people are willing to overlook that they’ve been shipping the same game for 20 years and charging more than most AAA games during that time frame. I also think BOTW and TOTK are wildly overrated - they’re padded out, clunky, with some of the worst mechanics in games (weapon stamina) on undercooked hardware.
But that doesn’t mean that other people can’t enjoy them.
