This isn't the kind of decision you want to make with haste. While at times, it is true that some people get into gaming to the point where it interferes time wise with work or chores, you didn't indicate that to be a problem.
Everybody needs something to look forward to during idle times, and even though video gaming is not as invigorating physically as say playing ball in the park, or riding a bike, the way your hobbies affect your mood is also very important.
Speaking of which, video gaming can also affect your mood positively or negatively, and often times it's due to the type of game you're playing, or something else going on in your life. Mixing up the type of games you play and taking breaks can help.
It seems like perhaps this feeling came about over the dread of paying the $50 every month for a long time, than the gaming itself. Have you considered trying to find a way to make up that amount each month by tightening your budget elsewhere or doing odd jobs?
When I was a kid I made spending money off doing odd jobs for neighbors like lawn mowing, shoveling snow off walks in winter, etc. Don't be quick to get down about it, you just might find another thing you love doing because of it. One door closes, another opens.
