I think it would be easier to ask what kind of "RPG" you prefer. It seems to me that you have a specific taste [~Munchkin] which is different to what a few here like, which is ok of course. But dont tell us that strength requiremts or weight for amunition is wrong. Particularly when in the case like Vegas for example you have a chanc to even tourn it off. We can explain you our point but we can not understand it for you
~ In gaming, a Munchkin is a player who plays what is intended to be a non-competitive game (usually a role-playing game) in an aggressively competitive manner. A munchkin seeks within the context of the game to amass the greatest power, score the most "kills," and grab the most loot, no matter how deleterious their actions are to role-playing, the storyline, fairness, logic, or the other players' fun. The term is used almost exclusively as a pejorative and frequently is used in reference to powergamers and to immature players in general.
Fallout 1 or Arcanum or Planescape or Baldurs Gate and a few more have limitations to give you characters. A reason for playing a specific set. Thats why you have limitations. A monk will not use swords not because he "cant"because obviously everyone can hold and use a sword but because its against his ethics or role as a monk. The same reason why he doesnt use any armor. You are supposed to play this kind of role. If you want not to bother your self with heavy weight then play a character with huge strength but dont expect him to be a combination of Arnold Schwarzeneger, John F Kennedy and Einstein. This is the approach of games like Oblivion or Fallout 3 where there is no or just lidle difference in characters.
Its like when people complain that Fallout 1 or 2 have not imersive visuals because they play in a top down perspective as like Fallout ever wanted to be "immersive" in the first place. With a Top down perspective the experience is more in a direction that you "guid" a character you "build". In some first person game like Fallout 3 you are supposed to BE the character not guide him but assume you are the person you created. For example it should be no problem for a very skiny and weak person to play in a role playing game a barbarian with muscles of steel and people without academic education playing a genius character with high knowledge in mathematics for example. The game decides if you are succesfull or not (the so called dicre roling) and not your skills with shooters or what ever. I know its a bit unclear particularly as modern games tend not to use any real category anymore and with terms that even could count Doom or Oblivion as RPG when they are action and/or adventure games. That people have a different preference is alright and neither you nor others have to explain why they like what they like. But you can not expect from us to accept it that others want to explain us why their preference is the best one and why we should like that as well.
