We share here our tables house rules, here some of mine: >D&D 3.5e (not always all enabled at the same time though) • Group alignment at chargen the group pick an alignment between L/G, L/E, C/G and C/E as the shared party alignment, the individual characters can take any alignment that is of one step deviation top from that (eg: group is L/G, available alignments are then L/G, L/N and N/G); • Iconic characters each pc has to have a combination of charoptions unique to his own, the only exception is picking "human" for the race; • Elite fallback when generating stats players are allowed to make 2 arrays using 4d6 drop the lowest and selecting one between the two and the Elite array (15, 14, 13, 12, 10, 8); • Called shots are sunder attacks using the rules for sundering a carried or worn object and the localised damage optional rules from the DMg p.27. Making a called shot with a ranged weapon requires to be in 30ft or less distance from the target and counts as a full attack action. You can't make a called shot against creatures immune to critical hits; • Roll for Common there are multiple "lingua franca" in the world, each specific of the regional mercantile clusters and each of them requires a roll on the Speak Language skill (much like in SpyCraft) using the Decipher Script skill rules (CD is determined by the information complexity, cultural familiarity and degrees of separation, like geographical distances); • Feats retraining during character advancement it's possible to swap a feat for a new one or a chain of feats (up to a number of feats equal to the feats total available for the specific level) extending the timeskip necessary for the advancement and, optionally, expending money for training, as specified by the optional rule for training cost/time at p.197 of the DMg (Learning Skills and Feats); • Skills retraining as for Feats Retraining, the maximum number of retrainable ranks is equal to the rank cap of the specific level. You can't reduce a previous known skill at 0 ranks though; • Falling stunt fall damage is applied normally unless the character has no means for mitigating the fall (eg: being at arm reach from a wall), in which case the effects of localised damage (DMg p.27) are applied. On top of that if the character is free falling from more than 400ft the falling damage triggers a Coup de Grace; >GURPS • Secondary Traits Cap all derived traits (secondary attributes like Per, Will, etc.. and Skills) are capped at +30℅ of their main Attribute score (eg: with IQ 10 the maximum related Skill level is 13). Advantages (eg: Talent) can be used to break the cap; • Reduced Disadvantage Budget the point total available from disadvantages is set at 30% (instead of 50%) of the Character Points budget; • Combat Reflexes fix the Enhanced Defense bonus included is no more; • Armor fix the optional rule for edged weapon damage from the Low-Tech is enabled; • Strength discount for high TL for each level above TL 8 the cost of Strenght gets reduced of a 10℅ (capping at 40℅); >Stormbringer (and other related d100 roll under games) • Blackjack resolution (taken from Delta Green) in case of opposing rolls the roll result more close to the TN wins; • Dubs (Taken from Hârnmaster) a result of doubles indicates an extraordinary outcome (critical success/failure); • Push (Taken from CoC) if you fail a roll you can push your luck for a new roll risking a critical failure; • Skill synergy instead of rolling at default if the character has a skill thematically related can use that instead at half of its value. If does so cannot get skill advancement for both, cannot score a critical success nor push;
