As the Beta period for the incredibly fun Team Fortress 2 winds down, the website Rock, Paper, Shotgun offers up several pieces on the title. If you played the original TF and want to know how things have changed, they've got an in-depth series of posts on the nine classes. If you're more interested in the evolution of TF2 as a concept, the first of a two-part interview with game designers Robin Walker and Charlie Brown highlights the long road between there and here: "The arc of TF2 is something that's probably familiar to a lot of amateur developers or designers. When we got here the first thing we built was overly complex, very hard core, almost impenetrable to anyone who wasn't familiar with FPSs in general. And as we found as we played it, wasn't more fun because of it. I think one of the things we've learned as designers over the time we've been here is to better preserve our ideas while still making them more understandable ... If I looked back at various designs in the different versions of TF2, then I think that's the thing that moved the most. We were always doing interesting classes, interesting weapons, but I think the thing we succeeded at the most, that we were failing at the most, was that nugget of acceptability relative to depth." As for the best class, I tend to agree with Jerry.
