Pay to play no longer guarantees no microtransactions. There are plenty of modern games that charge 60+ and still contain ingame stores, battle passes, lootboxes, etc
Thing is, there's plenty of Premium games exactly as you describe - it's all I play on mobile or tablet - but they all cost on average between £5-10. Many are ports, some are free to install to play the first couple of levels and then you unlock the game with a one off purchase. The only thing I own good enough to play games on is my tablet and phone so I know this the hard way, but quality is out there, it's just hidden away.
Anyway, £60 is a big step up from the usual £10. I think the Final Fantasy/Ace Attorney ports are about £20. Usually the cheaper price to my mind is that you're playing on a smaller screen and with a touch control system that doesn't always suit the game you're playing (although it can improve certain games - Cultist Simulator, Kingdom Two Crowns and Bad North all feel like they work better with touch controls for me but that's more a genre thing)
Yea, but here, that 60 bucks also gets you the full macOS version of that game.
For sure, it is pretty steep by itself if you only game on mobile, but if you look at it as including a version for your handheld when you buy it for PC... it's pretty much what Steam already does with the Steamdeck, which makes sense to me.
Now the price itself, yea, I find it a bit expensive, even on PC/Steam and I'll probably wait to grab it on sale one day.
Yeah, I guess if you own an iPhone and a Mac there's more appeal. I see the prices for things on my son's Switch and he's not old enough to want the really expensive stuff yet, and you don't even get a desktop version there.
I think my original point stands though - that having "you buy it and then you play it" games on mobile is not a new concept.
