Nobody's going to be able to answer this question for you. Everybody is in a different financial position, and will have different priorities.

You have to decide if it's worth it, but I honestly don't see why the $75/month needs to be the issue. I can see maybe if you're deliberating over spending the 4x($30-$40) on the game purchases, but the monthly fee is, well monthly, so you can just cancel next month if it isn't working for you.
