Following the advice to be well versed in the different kinds of RPGs before attempting to make a heartbreaker. What RPGs (or near RPG) would you suggest?
My guess at a comprehensive list:
One cannot make a comprehensive list within a single post...
A few worth getting a feel for
Blood & Honor or
Houses of the Blooded (same engine) by John Wick.
Monsters! Monsters! and
Tunnels and Trolls either 1e+5e, or Deluxe of each. One engine, 2 games. Ultralight combat, but players are supposed to be allowed to try wacky or nifty tricks, the GM sets a difficulty. 1st ed of T&T was 1975... and unlike Traveller, it's ALWAYS had copies available.
Traveller: Classic is still rocking; Mongoose's version is more modern, but equally solid. Whole editions (Except Mongoose's) are sold by Marc Miller on CD (or if requested, thumb-drives), $35 per disk for PDF (farfuture.net) MegaTraveller has mass combat that works very much like personal combat.
At least two different Very-light/ultra-light games:
Cosmic Patrol,
Risus,
My Little Pony Tails of Equestria,
Lasers and Feelings,
3:16 (there are several more)
A couple solid storygames, such as
Cosmic Patrol,
3:16,
Grey Ranks,
Fiasco,
Once Upon A Time. (Note:OUAT is NOT an RPG, but it is a storygame. Fiasco being an RPG is argued by some; I don't consider it an RPG. But Fiasco is very much a storygame)
Palladium's The Mechanoids, The Mechanoid Invasion (in The Mechanoid Trilogy). It''s a very playable ruleset in a rocking setting.
Is the goal primarily
- Exposure to different systems
- History of the development of systems
If (1) then use the latest versions. Like there is no reason to play Spirit of the Century if you want to know how Fate works, because modern day Fate is a way better game.
If (2) then we need to start looking at publication dates.
There are several game lines where each edition is a new engine.
Traveller is a great study: CT 1e in 1977, CT 2e in 1981, MegaTraveller in 1987, Traveller: The New Era in 1992, T4 in 1998. T5 in 2015 MGT 1 in 2008, MGT2 in 2016? MGT2.1 in 2024. Plus official ports to d20 (Called T20 Traveller's Handbook), GURPS, and Hero System.CT 1e and 2e are the only editions which are truly compatible, but MegaTraveller is convert on the fly. T:TNE is technically a port to 2nd ed Twilight 2000, and many things are convert-on-the fly. T4 and T5 share the same underpinnings...
The 1986 "Traveller: 2300" is a related game, different setting and tech assumptions.
Dice by Edition:
CT, MT, T4, T5, GT, HT: d6's only
T:TNE: d6's d20's, and faking a d16 using a d20 and rerolling.
T20 THB: full poly set.
T2300: d6's and d10.
