Sometimes I get stuck on a boss. A ridiculously hard boss. I'm not that much of a fan of super difficult portions of games that require absolute perfection, almost like 3 starring Mario Kart 8 at 200cc level of difficulty just to progress in a game. I'm looking at you Hollow Knight. I love your gameplay, but you're making me become an expert at dodge and parry and I just want to run and slash and get new abilities, yo. So I put it down months ago, and every time I look at the game I'm reminded that A, I have to beat that boss, or B, I have to figure out where I was and with a map that big that's going to be a grind.
Instead I can just boot up my Rocket League and keep trying to make Gold rank. It's mindless and reflex based and doesn't require too much of me.
Now, if I had more hours in the day to game, I'm sure these things wouldn't be a problem. But with barely an hour or two of gaming per day after I work and get all my extracurricular stuff out of the way, that's really what I'm left with at the moment.
And this isn't just Hollow Knight of course. This has always been a thing. Sometimes it's just because a new game comes along that I must play. Final Fantasy XII on the PS2 still calls at me sometimes to finish my file, but once the Wii had come out I never turned on my PS2 again.
There's just way too many games, way too little time, and yet each of us every day is still begging for the next new thing. We are insatiable and no wonder why: we never finish what's on our plate.
