I always find it best to start with an archetype and tweak it to make it something like what I want. The math/crunch of character creation in M&M has always put me off the game which is weird seeing as I rattle off characters in DC Heroes with no problem (also point buy, but less fiddly I find). Not for lack of trying either - my shelves are groaning the most under the weight of Mutants and Masterminds stuff despite the fact I've only played it a couple of times and never run it. Doh.
