If you have one large cage with a colony of 3+, your gliders will be fine without much attention from you other than feeding and watering and cleaning. If you can manage that and also give attention on the weekend, then you are doing ok. Most owners do not play with them nightly to be honest. And that is certainly moreso the case when you start having numbers above 5 or so. With 17 in my keep, they are lucky to get a hand fed sunflower seed or a pat on the head daily.
