As it seems, those who like roleplaying and therefore stretch the rules or ignore them at all, are the first who scream aloud that those who are sticking to the rules are only roling dice and do no roleplaying at all, something I think is quite interesting. Given the fact that those who roleplay so great and have a fantasy that is unimaginable are the first that deny others the possibility to use both roleplay and rules...don't get me wrong but I think it is nearly always the same thing in such discussions. -Just think a moment about it. The Good Roleplayers must always be convinced that there is a mid-way, using rules, diceroles and roleplay together.
I know you can try to roleplay many things, but I think you can't roleplay characters with ability scores like INT34, WIS30, CHA36, DEX28 and so on, therefore you have rules. The same goes for CHA8, if you try to make him appear more social then he is then the skills, rules and dicerolls will prove wether he is or he is not.
I pointed out on some other boards in discussions that went the same route of argument, that it is nice keeping your skill points save from those boring social skills, you can use them much better for skills you can't roleplay, e.g. spellcraft, concentration, craft(...), saves you a lot points, this statement is somehow insulting those who don't do that, but sometimes I think this might hit the spot as well as only wanting to make a good roleplay!
I played AD&D 2nd as well and sometimes I thought, what stupid rules they have and how unbalanced are those classes, skills... especially after starting to play D&D 3rd.
I think games that are fair and balanced, are more fun to play for everyone, I played very unbalanced games as well and as long as there are no numbers dices and the like involved it is fun for everyone most of the time, but when it is getting down to numbers you will recognize the fact that the players with the 'weaker' characters will posibly end up annoyed because they can't do anything or are always worse in doing things than those with the priviledged characters that form the upper side of the group.
That's why I dislike groups with great powerlevel differences and roleplaying things, that can be done with a dice role and roleplay by the rules, as well.
