I haven't looked intensely at a lot of systems, but from my perspective as an occasional gamer, Bundles seem like a useful concept, since it gives you a framework of several traits to build a character on. This could be good for generating character concepts, if one doesn't have one in mind, and it's also less daunting perhaps than picking from a long list of individual traits. Mind, this is mostly coming from my experience of the painfully complex Hero System. Too much math, 8 zillion stats, j00j says DO NOT WANT.
