Vampire Survivor.
I began playing it after so much praise from all over the place and it just uses predatory tactics to hook the gamer. I only had fun with the game for maybe a day or so but overall clocked in many more hours of hate-playing. The only good thing is that the developer (who's background is developing gambling games) does not use those tactics for microtransactions.
Once I deleted the game, I was never even tempted to go back.
And why would Microsoft fix those when their paying customers even work for free?
