At long last I've been invited to play an RPG, not as a GM, but as one of the player characters! Huzzah!
And Call of Cthulhu, no less! Awesome.
...As someone who's run many different games over the years, including Mythras, I do have to say that the Call of Cthulhu dice mechanic seems... brutal?
Now, of course, that's the whole point, right? The genre is cosmic horror: your characters will die horrible deaths or go insane, inevitably. Sure.
But... Here are some things that make me less excited about getting too invested in my character:
- the Dice mechanic is d100 roll under your skill. Okay, I'm familiar with that (former WFRP, Dark Heresy, Unknown Armies and Mythras player).
- the Critical failure range is 96-100 (or worse, depending on your stats). The critical success range is... 01. So already, you're more likely to critically fail than succeed. Okay, horror etc...
- There are clear difficulty checks: regular, which is you roll you skill straight up, half your skill or 1/5th of your skill. There are no beneficial modifiers.
- While there IS an advantage / disadvantage system (re-roll tens die, for good or ill), this purely GM fiat. They can totally have you roll your skill at 1/5th it's rating WITH disadvantage too. Ouch.
- Upgrading skills means you have to PASS a skill check first, then roll to FAIL a skill check after the game is over. This makes it pretty hard to level up poor skills (in Mythras, it's different; when you fail a check, you get to see if you level it up after the game is over, and even if you fail, you still go up 1%).
So... in this game, odds are you won't really improve much and there are no ways to get beneficial bonuses besides GM calls.
This doesn't seem like a very fun system to play with, I admit. Even WFRP 1e had a bit more going on in it.
What am I missing? After 40 years of game design evolution... Call of Cthulhu still seems "stuck".
Maybe it's a OSR thing?
I'd rather play Dark Heresy 1e, to be honest. Grim and Dark as it is, at least there are ways to negotiate a +10% to a skill check once in a while.
