d20 modern Failed...why? (or did it?)

[The Shaman]

D20 Modern suffered from being too generic. While the rules were sound and fun (I still play it) it has no real "core flavor" to it and thus it can be very difficult to determine just what and how to run it for a GM.

I found the exact opposite to be true: it was extremely easy for me to come up with a campaign idea and tweak d20 Modern to fit it.

My favorite d20 game.
