You might possibly detect a note of bitterness, there, Jim. You see, M&M killed his parents by sabotaging a trapeze when he was just a lad.
One note of interest for me is that there seem to be some people who judge the system by its performance in character creation, while others judge the system by its performance in play after character creation. Yes, everyone does both to some degree, but there does seem to be some distinction, and not necessarily along party lines.
I like d20 Modern at both, and I like M&M at both (now that I understand it). But I'd say that I like the complexity of M&M for character creation, because I can take a lot of time to really make exactly what I want... and then gameplay is usually fast and furious, whereas d20 Modern has faster character-creation time, for me at least, but combat tends to run a little slower.
That's all just me, of course.
