Massawyrm, one of the reviewers on Ain’t It Cool News, the premier geek media review site, was a playtester for 4e. Now that “D&D Experience” has happened, there’s huge amounts of 4e rules info available out there and also the playtesters are released to speak.
The review is maniacally positive. I hate to be negative, but I worry about the subtext in a lot of the bits he talks about. From flavor (is it appropriate to call one of the monster roles “artillery” in a medieval fantasy game?) to too-obvious WoWisms (“elite” monsters?) to game mechanics (at epic levels you rez all the time and have powers like “once per day when you die, you…”)? Well, I hope he’s right I reckon.
