Warhammer Fantasy Roleplay
In the grim, dark, grimdark fantasy version of Early Modern Germany, you will roll up peasants and be slain by fantastical creatures and Daemon lords vastly more powerful than your character can ever hope to become, no matter how much experience he gains. Unless you have the Tome of Corruption supplement, in which case, you can be a badass motherfucking Chaos viking.
Either that, or he'll just die of cholera.
Warhammer Fantasy Roleplay is, as its name implies, a roleplaying game set in the world of Warhammer Fantasy Battles. It has had a checkered past, going through a number of different publishers and frequently sitting for years in development limbo.
Although the setting is occasionally Tolkienesque, it generally takes far more inspiration from the real world, being essentially an alternate universe version of Europe circa the 1500s. This means that firearms are fairly common but also fairly inaccurate. Similarly, magic exists, but it has a chance of raping you with eldritch energy. Humans, as well as their dwarf and elf allies, are opposed by beastmen, orcs, daemons, trolls, and all manner of other horrible things that may inflict loss of life and limb, usually with far darker interpretations than their Dungeons & Dragons counterparts.
Nearly every portion of character creation can be rolled leading to amusing tales of a peasant, a noble, a doctor, and a sailor getting together to claim a lost dwarven stronghold. The best class is ratcatcher, as it has the most important piece of equipment in the game, a small but vicious dog.
The system in general, especially in combat, is extremely (and often hilariously) lethal, and has many rules for crippling injuries and critical hits. This can cause, for example, a lowly badger bite to result in the loss of limbs, and turns attempting to mount a horse into a dangerous endeavour only undertaken by the most foolhardy of warriors.
Fantasy Flight Games have recently announced they are bringing out WFRP 3e, which has whipped /tg/ up into a storm of trolling and RAGE as it appears to have almost completely abandoned the 2e system and has begun using "Custom Dice", "Action Cards", and premade character sheets, leading many to comment it looks more like a board game than a true WFRP successor. If one is able to get past their own nerd-prejudice, they will see that the latest edition is arguably the best iteration of WFRP yet - none of the broken looseness of 1st, and free of the crappy setting of 2nd. There's also remarkably little rules bitching, since everything is on the cards and the books never need to be summoned. Board game it may appear to be, but roleplaying it is to the core.
