We ramble a lot about free games, which is to be expected on a site that fosters the growth of free games, but what about published games you gotta fork over some scratch for (if you wish to be legit, that is, we'll assume you do). I'm sure we all get our influences from these kind of games, at least inspiration of game mechanics. What are some of your favorites?
(I'll only list one to get started, I don't want this to be a wall of text)
WarHammer Fantasy Roleplay: I'm sure I've rambled long and hard about WHRP, but really after a little over a decade and a half of gaming this guy is always my fallback favorite. I grew up in the WarHammer world, playing Fantasy Battles since I was a tyke. Now the Roleplaying game allows my players and I to explore the vicious and grim world of the Empire.
Setting is a huge factor of the game's appeal. It's GRIMDARK™ with sprinkles or heapings of dark comedy, which takes a lot of cues from Medieval Germany. Rife with xenophobia, religious intolerance, and corruption in every citizen it makes for great and complex scenarios.
The Mechanics of the game are great, in my humble opinion, using only 2d10 in percentile. Many criticise this system as being too harsh on the players, but I argue that's the point of the game. Your characters aren't grand "heroes", they're just scum trying to survive and it's really hard for them to do anything of real worth. If they're able to bludgeon the Cult Leader to death with a table leg and a shovel then it's a good day. WHRP's other mechanical plus (and vice to others) is it's use of tables. Tables after tables, for every single thing you can imagine. In fact character generation is 100% random, down to your race, career (of which there are OVER 250), name, how many warts are on your face, etc. The critical tables are graphic and juciy to describe to your players when they slice a bicep off a Beastman Gor, or when a Chaos Warrior tears a players arm off with stringy tendons trailing after. It really gives the player the feeling that WarHammer is a very fatal and unforgiving world, which makes most players (operative word: most) think twice before charging into battle. Many of my players try to find indirect means of succeeding confrontations instead of charging in rusty swords held high.
Overall, one of my favorites in the book.
Note: I have been recently trying FFG's 3rd Edition of the game, which tries to revolutionize RPGs in general by implementing tried and true mechanics of their many successful boardgames like Runebound and Descent. We;ve onyl played one game so far but it's kind of a headache. The necessity for handfuls of dice (on average you're rolling 6-7 custom dice for even the most BASIC of actions like Observation), paired with the integration of "action cards" gives it a weird feeling that isn't so much an RPG as a really expensive and complex board game. More on this as we play.
