I did 5 (yup, Five!!) Minecraft quilts this year. Three were for brothers, and I quilted those with slightly wavy lines going across the quilt. I didn’t want the stress of staying parallel and even to the blocks and I was in a hurry. It worked well.
The other two are for my daughters and I did those in a meander. I’m much happier with the meander.
I’ll try to post a photo.
