Class and Level Systems

In keeping with yesterday's table comparing ability score names across multiple early system, I thought I'd do the same for other terms common to class and level systems. I dropped RuneQuest and Traveller from this chart, since neither has classes or levels. I've added Rolemaster, since I at least remember RM used the terms "class", "level" and "experience points". However, I don't remember for sure whether it had the terms "hit dice" and "hit points", and my knowledge of Tunnels & Trolls terminology is kind of hazy, too.

I used to run TFT, so I was able to be more definitive with that column. TFT had experience points, but these are traded to increase ability scores, so TFT is a class system, but levels are only implied. Similarly, TFT tracks damage against total hit points, but total hit points = ST.

D&D	T&T	TFT	Rolemaster
Class (3)	Class (3)	Class (2)	Profession (20?)
Fighter	Warrior	Hero	Fighter
Magic-User	Wizard	Wizard	Magician
Level	Level	n/a	Level
Experience Points	Experience Points	Experience Points	Experience Points
Hit Dice	n/a	n/a	Body Development Points
Hit Points	(CON)	(ST)	Hits

Again, shaded cells in the same row indicate the terminology is identical. I'm pretty sure T&T used the terms "class" and "experience points" and had concepts that matched the others, but I'd like confirmation, as well as confirmation for Rolemaster, if anyone has that information. Basically, I'm looking for:

• Did that system use the concept?
• What was the concept's name?

I've restricted individual class names to the primary combat and magic classes, since the others jump around quite a bit. I don't remember how many classes Rolemaster had in the main book, or what the names were; I think my friend who ran Rolemaster actually only bought individual supplements (Arms Law, Claw Law, Spell Law) anyways.
