Psuedo-Quasi-Intellectual review of Alternity

Psuedo-Quasi-Intellectual review of Alternity Science Fiction Roleplaying System

Alternity. The final roleplaying system to emerge from TSR (much of the supplementary material was printed under the TSR, a division of WOTC trademark) was crafted from the start to be a classless, skill based science fiction set from the modern era to the far future. With the addition of material in Dragon Magazine the system could actually be pushed back to the 1800s, potentially even as far as the Renaissance era if you tried, and out into horror and b-movie genres. There was even material to convert D&D Characters, monsters and gear to and from the system.

Published Settings
  • Darkmatter - Take X-Files, make the heroes work for a non-profit with no governmental sanction and youre looking at the basis of DarkMatter.
  • StarDrive - Space Opera in the 26th century, on the newly reopened frontier. This was actually the most supported of all the official settings.
  • Gamma World - Poor Gamma World, yet again the red-headed stepchild of the family, the game only ever had the core setting book printed and one Dragon article that I know of printed.
One of the coolest features of the ruleset was the degrees of success. Instead of merely a binary result you had the possibility of; critical failure, failure, ordinary success, good success and amazing success. This allowed for one of my favourite systems for handling firearms Ive encountered. Striking a bargain between heroic action like D20 where gun shot wounds can be laughed off and the realism of Gurps where bullets flying gets people dead real fast, Alternity allows for dangerous but not automatically deadly combat. Wounds degrade your ability to act successfully, without the binary status of up and acting or down and bleeding out that HP systems are notorious for.

Tying into the levels of success was an innovative die mechanic that took in account difficult of task without changing the target number. Instead of moving the target number around to show different difficulty, a control die was changed. With the goal to roll low and the player always rolling a D20, adding or subtracting dice to the roll was a straightforward idea, supported by a great diagram.

Mao Xiu is a strange system as the asteroid belt and the moons of Mao Xiu III are the primary sites of interest. Rumours of strange objects found drifting in and among these sites have only fanned the speculators who have flooded the system.

4037 Revati II is a  marginal world that is composed of (from the human point of view) sealed habitats and dig sites. Valuable primarily for an abundance of rare elements in concentrations to make mining viable, the planet is surprisingly unexplored beyond basic orbital scans.

[Stars Without Numbers] Wanderers in Darkness pt. 1

Wanderers in Darkness is my SWN campaign for an episodic game at the monthly club.

However Im not going to stick with just the rules as written. I want to add a little more heroics then I think the rules are designed for. One of the elements I like with Savage Worlds is the concept of bennies. A simple limited number of rerolls is the easiest to implement, so all characters will start with 3 bennies for the 4 hour sessions. On the other side I'll have 2 + a bennie for each player.

Additionally there is quite a bit of gear from SWN, Gammaworld and Mutant Future that I want to finally see in play. As cool as Serenity/Firefly is, I want more tech in my sci-fi. I plan to steal from Alternity and provide PCs with a piece of gear that is distinct to their concept, for example a battle hardened marine would feel naked without his old service armor.

Not exactly a rule change but I plan to havd players explain how they fail when they blow a die roll. I want failure to be as interesting storywise as sucess.

More as I create worlds

kicking the Rust Off

My its been a while since i posted on here. I'm finally getting into the swing of working second shift so I need to get back to writing on here.

1) Sector creation for the sandbox Stars Without Numbers episodic campaign I will be starting in days.

2) Learning how Only War (roleplaying as Imperial Guardsmen in the Warhammer 40K universe) differs and interacts with Dark Heresy and Black Crusade

3) Possibly learn enough Gurps 4e gor a one shot.

4) Learn Wild Talents enough for a non super hero one shot, perhaps something along he lines of Kimi from Happy Jacks Podcast Skyrim themed Dragon Brothers game.

5) Source a rule system for the Birthright/Council of Wyrms mashup running through my head.

Keep an eye out...
