So I realized when I was talking to Toby about his character that the d20M system was already 7 years old when we started our game, and 3 years out of print... and we've been playing for 12 years beyond that. The system we are using is old enough to vote!
What would you think about switching over to a 5e system? I wouldn't want to do the UA d20 Modern conversion, because that just adds some modern spells and equipment to the same classes from D&D.
But I did some looking, and I found a guy who did a much more true-to-form conversion. You pick your base class (Strong, Tough), then the subclasses are d20M's advanced classes. We'd have to come up with a way to multiclass, but I've already got some ideas for how to make that work. I'm sure there are some other areas that are missing, but we could fix those as they come up (skills might need a tweak, for instance, and some of Frank's gun feats would need to be ported). His stuff is all here:

Let me know if you would be interested in converting, and if this looks like it would work. I'm fine either way, since all of the content I've prepared is generic and I find stats that fit in the moment. If we do want to change, now would be a good time to do it, then we can start this chapter with the new versions.
