#19: Favorite Supers RPG. Mutants & Masterminds. It was really quite well done, and is a lovely, lovely book. Granted, I bought the first edition, and because I've played it very little, I've never gone for the updates/upgrades. I'm a little irritated, actually, by games that update too often (d20 Star Wars is another really bad example), but I don't know that the upgrades are really significant in terms of major shakeups to the rules. I'm a little unclear on what the settings for the game ended up being produced and by whom, but that's OK—as much as I like settings, I don't actually need them, and I almost never use them as is.
#20: Favorite Horror RPG. For one-shots: Dread, absolutely. For campaigns, Call of Cthulhu. I'm not actually a fan of the BRP system, though—it works well enough if you can get past the bizarrely Byzantine chargen activity, I suppose. The d20 version is (surprisingly, at least it was to me when it was new) quite good. I think it's important to limit level advancement either via slow advancement and time-bound campaigns, or something like E6, though.
#21: Favorite RPG Setting. Assuming that home-brews aren't meant to be picked here, I'll probably say Iron Kingdoms. There's a few things about it that I don't like, but not that many. It really hits most of my high points without much in the way of low points, and I really love the tone of the setting especially. For second favorite, I'd probably have to pick the Warhammer World.
#22: Perfect Gaming Environment. Ideally, I'd game in a large conference room without windows. Dark wood paneling on the walls, decorated with large prints of fantasy art (the Larry Elmore BECMI covers, or some big Wayne Reynolds, or some big Frazettas, etc.). A big, round, hard-wood conference room table in the middle, surrounded by large leather-upholstered chairs. Maybe some stuffed animal heads on the wall. A wi-fi environment where the GM can play music and/or sound effects from his laptop during the game. Flickering faux candles for lighting. Imagine a classic Victorian British gentlemen's club, like the Drone's Club, but with a fantasy twist.
#23. Perfect Game for You. This is an odd question, because I imagine anyone who blogs has already talked—probably ad nauseum—about what the perfect game for them is. For me, it's m20. And, ideally, I'd be running it, or playing in a game with a GM that runs just like me. In my home-brew dark fantasy setting, played as a swashbuckling/horror pulp hybrid.
#24. Favorite House Rule. Probably gotta be Action points. The way that I run them, though—the original incarnation of just adding a d6 was too weak to be meaningful. Make it a d10, and make a healing surge one of its applications; and make them reset every session instead of every level—and you've got something that really works.
