For old school stuff, I maybe buy a couple a year, at most, can't really afford to with their prices, but with new games, I am basically buying one a month, I'm having a great time. Dead Space, Resident Evil 4, Dead Island 2, I got Metroid Prime on the backburner at the moment, I grabbed Sons of the Forest (Mildly regret), that's just the past 4 months, and I got Zelda: Tears of the Kingdom in just a few weeks.
For me, I feel like I have "game moods", where I'll pause certain types of stuff, take a break from it, and then come back to it later on. Sometimes you get burnt out or things aren't vibing right and you just need to step back, go do something else for awhile till the interest sparks back up.
