As for stats, I'm fiddling with this...
Arm (w/little arm bicep symbol) - Str, +melee, thrown objects.
Leg (boot symbol) - Speed, Move rate, dodge
Eye (eye symbol) - accuracy, to hit+
Head (brain symbol) - IQ, resist mental attacks, +magic
Heart (little zelda heart) - Toughness, Hits, HP. Maybe resist poison...
Mouth (smile) - Charisma, though I might not use this stat at all.
Armor (little shield) - Defense, resist physical attacks that are not dodged.
This is for a super hero/sci fi thing I'm in the beginning stages of making. I'm not doing any leveling. I am planning on making the 'missions' short and diverse. 30 mins, 5-9 levels or so.
For a Fantasy Squad RPG I was messing with I was thinking of going statless, but your starting class decides what you can use. For example
Fighter - use heavy weapons and armor, no scrolls or wands. Strong start.
Mage - Light armor and weapons only, can use any scroll, book or wand you want. Weak start.
Thief - Use 'tools' for picking locks and disabling traps. Use medium armor and weapons. No shields.
Cleric - No edged weapons, heavy armor. Can use holy relics (heals, shields, turn undead). No dark magic wands/scrolls
Combat would be a simple Weapon + Die Roll - Armor = Damage. Spells ignore armor.
All characters start with 100% health, mana is not used as wands have their own charge limit and Relics, Books and Scrolls cannot be used while moving.
Hope that helps...it can be fun designing RPG systems but I recommend getting on with it. Many people languish in the design phase and do not program anything.
