No one really touched on this topic on the special edition thing...well, aside from jimduckie and Mad World.
The fact that recently, as I was checking out the state of upcoming games, I noticed that a fair amount of Special or Limited editions have been coming out with expensive DLC out of the package. Dante's Inferno's Divine Edition for the PS3 for example, not exactly a special edition, but comes with a new level that isn't available right off.
Not all games have DLC that's worth it, such as Mass Effect 2 having just weapons and armor, also Zaeed, the latter available on a regular new game too, $15 if not. As well as Dragon Age having the 'buy the game new, now' incentive of that $15 DLC 'the Stone Prisoner'. If you look ahead, it's getting more common for that stuff to be skipped on a mere new copy, but added to a special edition. Since most are between $10 and $30 more, and the DLC can be worth similar, sometimes it's a good investment. Sometimes.
I'd predict it will become more common in the future to have the specials, limiteds, and other such versions come with DLC worth at least as much as the cost hike, since it'll cause a scramble to buy up as much of those editions as possible by those who want that DLC. Conidering that any DLC that offers such things as levels and whatnot upon release just screams 'it's unfinished, pay us more to finish it', having that stuff with the specials mitigates that problem, if only slightly.
Some of the DLC they've been releasing is pure garbage though, multiplayer characters aren't worth the extra $20, even if it comes with a poorly made figure.
As for character design Gausswerks is pretty forward as to making characters lasting and recogniseable. Too many games have either overly generic character desgins, or way over done designs that prove to just screw up framerates or make the whole thing a clusterf-ck.
