Well, we were expecting some response to A Heavy Problem, but we severely underestimated just how much interest everyone had in contributing. If you're one of the many folks who emailed us proposals and haven't received a response, please accept our apologies, because there's just too many for us to reply to all of them. From the large amount of feedback and forum activity, it's clear that many of you found this interesting, so we'll definitely be posting more design goals. For those of you still thinking about it, here are some more tools to use in evaluating ideas:

To continue from the previous week, today we have some additional finished trading card images for you to take a look at - the Heavy and the Medic.

As Gabe mentioned in his lengthy response to an email recently, the next class pack will focus on the Heavy. For the Medic and Pyro packs we kept our goals for the pack pretty close to our chest, but for the Heavy we've decided to open up the process a little.

During the development process with most of our games, we end up creating content that, for a variety of reasons, may never see the light of day. Sometimes we may not have the time to bring the content to finish, sometimes we use them as a company-only experiment, and sometimes the content just isn't in line with what we're doing at the time. Needless to say, there's a fair bit of cool stuff that we've never been able to share with our fans. We're happy to say that this blog has now given us a unique format in which to share some of the unused artwork with you.

In any game there's often a bunch of hidden complexity behind some of the simplest looking features, and TF2 is no exception. One example is that of the Medic's medigun. From a player perspective, it appears simple enough: point it at a team mate, press the button, and it'll heal them. After playing with a bit, most players notice that they have to stay near their target and maintain line-of-sight to their target. After playing with it a lot, some players notice that there's some variability in the rate at which they heal their targets. I thought it might be interesting for Medics to explain what's going on here, and why.

When producing concept art, our artists believe in providing a variety of options for any given subject. A single concept rendering would place too strict a constraint on the resulting game design.

Now that we've settled into regular releases of content, we've found ourselves wanting a better way to talk directly to the TF2 community about the state of the game and some of the reasoning behind the choices we're making. Our hope is that this blog will accomplish that, and give everyone some better insight into our development process as well.
