As someone who has supposedly rp'ed as long as you have, I'm quite disappointed that you don't seem to have picked up on a key point of roleplay: it's very definition and method of play varies drastically that one form of rp may not be recognised as rp by another and vice versa.
I've seen no such thing. The systems may be different, and the settings may vary massively - but the experience is relatively the same across the board.
For instance, many roleplayers play the game for loot and stats, they are not so interested in playing a character as they are building up their stats, often refered to as rollplayers since it's all about getting the right stats for their dice rolls.
We look down upon them. We always have.
Another group of roleplayers play roleplay games in order to play a character and might not even bother with stats or loot, as long as people play according to their characters.
Exactly. Roleplayers. That's the point.
Now, your last point, it's completely wrong I'm sorry to say. If a player, while playing their character, puts forth an amazing performance of persuasion to try to convince an NPC of a course of action, should this then fall to dice rolls or should the player's performance be taken into account?
If your character is not persuasive, then your character is not persuasive. Ever. Period. The point is playing the CHARACTER within the bounds of who they are, and streatching that as far as it can go.
This varies from group to group, and larping shows that combat skills can also be treated the same way, as LARP requires the player to be competent in combat (or at least larp-combat) in order to portray his character's skill. So really, your one point is quite flawed...
So, your one real point is that LARP'ing nullifies my point? You're wrong, actually. Though I don't consider LARP'ing to be true RP'ing, I know many LARP groups that force you to act within the bounds of the character, and any actions you take are assume to be at the base ability of the character.
There was no "real" inventory system. We ddin't really write anything specific down and we took a lot of things granted when it came to what we had.
So, because you didn't use the system means that the system didn't exist? Like I said, unless it's homebrew, an inventory system exists.
ruleset for vampire masquerades that had comprehensive rulebook, but lacked a formal inventory system.
Not a subject you really want to debate with me, broham. I played VtM for years, along with a wide variety of the oWoD and nWoD systems. They ALL have formal inventory systems, just it's a different idea of "formal" and what constitutes "inventory". Generally, you know the equipment you carry, and have a "good idea" of what you have access to. It's still an inventory system.
Yes there are, Amber for one. Many White Wolf games, as they involve characters that probably have vast amounts of equipment, use a resource system instead where you roll to see if you have an item. Really you seem to have very little experience in pnp systems...
No, you roll to see if you have the funds to have the item (and any good storyteller will demand you have a good reason to have the item if you didn't previously declare it). There's a distinction. Anyone doing anything else needs to reread the rulebooks... I haven't even heard of Amber, though.
