i can't believe i spent all my money on five games, only not to play them...

The games I'm talking about are the Devil May Cry series, they were on sale on stream for pretty cheap but still, I bought them over the summer, played them for a bit, and then when school started I dropped them like a bad habit, I really do like the storyline of the game, the mini-boss fights aren't that bad either it's just something wrong with me, I get into something, play it for hours on end almost every day and then completely stop, do any other gamers have this problem?
