I feel you. It's really hard to carve out that time, and even when you do it's easy to fall back to the comfortable things--for me that's XCOM, Skyrim, and MGSV. It's important to not exert too much pressure on yourself, though, as that's how you grow to resent the demands of your hobbies, artistic or otherwise.
On the other hand, I know I wouldn't practice music or go on a run without some sort of structure, so there's clearly something to be said for forcing yourself to eat a balanced diet, metaphorically speaking. The question I always ask myself is why I feel a need to do this particular thing. Is it because I'm looking for comfort? Am I bored? Or am I actively excited to find out what happens? There's nothing wrong with pursuing a hobby simply because it helps pass the time pleasantly (wasting time interestingly is no waste of time), but it's important to notice the difference in your motivational state. So I want to ask you this: why do you feel a need to play those games? I suspect that when you answer that question fully you'll find out whether or not you actually want to play them or if you're feeling something else entirely. And remember, they are there for you, not the other way around.
Edit: for example, I have a big interview coming up on Wednesday that I'm really stressed out for. Is it a coincidence that I'm running a reddit death spiral while cranking out a new XCOM campaign and watching Starcraft 2 matches? Probably not, but that's okay because that's what I need right now. By the end of the week, I'll get back to mastering Bayonetta because that's been a great intro to fighting games for me, a non-fighting-games person, but right now it's fine that I'm doing the equivalent of shoving potato chips into my face. Everything in balance, including imbalance.
