I'm not happy with the huge attribute bonuses in Microlite75. The rules say to calculate by this formula:
Attribute bonus = (STAT-10)/2, round toward zero.
This means attribute bonuses range from -3 for a attribute of 3 to +4 for an attribute of 18. I don't actually use this formula in my games, but was talked into putting them in the rules because "most players expect large attribute modifiers" and because my table can't be expressed as a simple formula. I actually use this table:
This makes having "good attributes" far less important. Only a 3 gives a negative modifier and even someone with an 18 is only going to be about 10% better than average. Like in the original three booklets, a character doesn't need high stats to be effective. Even though it will meaning adding a table, I will be including the system I actually use in the next edition of M75 as an optional rule.
