Thanks for the shout, truly appreciate it!

That's huge, love the cat as perspective!

That's one of my Christmas traditions too. Though we watch the Patrick Stewart version of a Christmas Carol and a Charlie Brown Christmas every year

It's very possible to have parties with PCs in different power levels. Though it can become challenging during boss fights/combats. My recommendation would be to have the PCs at the same Power Level & encourage them to build to their theme. If built to theme the differences between the PCs will show

The system uses "Power Level" as it's system. The nice thing about that is that the character creation process is entirely classless. You get X amount of points per power level that you can spend on any attribute that fits. The system holds up for regular humans all the way to super heroes to DBZ
