I've reached a point where I'm only going to learn a new system if it does something that cannot be done with DnD 5e or another system I already know. That may change when I'm done building a system of my, own, however, because it's a matter of mental bandwidth.I'm just curious to see how people feel about new systems. Are you less likely to try a new game if it's a system you aren't familiar with?
