There is nothing wrong with taking a break and playing something else, starting a new hobby etc for a bit and then returning for new content.

That's what I am doing with WoW right now. I'll play it again when the next expansion comes out. I don't hate it - I just got bored. I'm having a lot of fun with FFXIV right now but eventually I will get bored there too and take a break while I play something else.

Rotating games that release regular updates keeps things interesting when the patch rate isn't quite enough to keep you entertained. No harm in that.

Not everything has to be a huge life changing decision. Leave for a bit, come back later, no big deal - it's a game not a marriage
