Attributes from 1 to 5, the One-Stat-Checks and the Two-Stat-Checks

The foremost attributes of a PC are commonly scored from 1-18 or so, and tested with a d20. This certainly beats the frivolous bean-counting you get from using d100s, but it is still too granular. I intend to score attributes from 1 to 5. 

- Agents chance of success are either the exact same or markedly different. This is desirable: It deemphasizes bothering over a +1 here and a +1 there and centres the fictional approach.

- Stats can easily be combined. 

One-Stat-Check: Roll a d6. Success if the result is less than or equal to the relevant attribute (Format: DEX CHK) (eg. You have DEX 4. Roll d6 result 5. Fail.)

Two-Stat-Check: Roll a d12. Success if the result is less than or equal to the sum of the two relevant attributes (Format: DEX+STA CHK) (eg. you have DEX 4 STA 3, summing to 7. Roll d12. Result 7. Succeed.)

(If d18s commonly existed, you could expand to those as well, but that may be overingenious)

Certainly, one could get carried away with this. Ah ah - picking a lock is a combination of intelligence (not that I use that attribute in any of my games) and dexterity. DEX+INT CHK, please. I have it in mind more for group actions. 

- d6s are ubiquitous and can be got cheaply and shared liberally. They can be rolled and read en masse - important, as I intend my system to emphasize mass parties and deemphasize the potency of individual PCs.

- The low numbers can be integrated directly with other subsystems, rather than converted to bonuses for that purpose.
