SYSTEM FINDER THREAD.
You say what you want to play, anon recommends you a system to do it in.
Systems:
NEMESIS is a free horror system, designed for CoC-esque adventures. Good if you have a horror setting but no rules!
Into The Odd is a weird fantasy setting that's just begging to be rolled up into a campaign on the spot. Use some OSR resources (like Goblin Punch) to fill the gaps.
Requests:
I'm looking to run a mech western. A western where operating giant walking robots is a central mechanic.

I imagine you could probably use Battle Century G pretty easily, or maybe use Strike! RPG, or even use Remnants RPG with some modifying and reskinning

GURPS
I want the most gurp-like rpg that uses linear dice

Ask in the GURPS-general which pyramid issue has an article on alternative dice. Play GURPS using those rules.

Wild West (or Wierd West) with an OSR foundation?
