What's The Difference? The Various T&T Editions

This list was swiped from the T&T Trollbridge Forum in response to a poster's questions. The answer was written by Aramis of Erak and can be read here. I've edited his words slightly, so my apologies to Aramis.

4E and earlier have lower dice for monsters and weapons, and Rogues are limited to 7th level. Original Monsters! Monsters! (M!M!) is 4E variant. Citizens originate in M!M!... but are different in 7.0.

5.0 is the 25 year baseline. M!M! 2E is 5E subset, but with only 2 types: Monster and Citizen. Shorter spell list. Loads of monster races with special abilities.

5.5 adds options in the back: skills ala Mercenaries, Spies, & Private Eyes; an additional statistic (WIZ); with the optional SPD stat being made a prime; TARO for stats.

6.0 is a fan job. it's got loads of little differences.

7.0 is essentially a redesign from first principles. Same 8 stats as 5.5 and same basic combat mechanics as 5.X. Spells differ in casting procedures, level requisites, and spell lists. Adds a different skill mechanic, Ken's Talent system. Types are: Warrior, Wizard, Specialist Wizard (4 sub-types), Rogue, Leader, Ranger, Citizen. The Citizen here is different, and less limited than the M!M! one. There is an implied extra type (monster), but that's a debate for another day.

7.5 nerfs the talents, and lessens the experience costs. It's better edited than 7.0, but is essentially the same except for talents and experience costs.
