I don't quite follow. Are you saying that the player is something that never develops throughout the game if his INT, STR, etc., is not increasing?Partly, yes. One removal of a defining characteristic is the removal of potential development.
Even in pen-and-paper games with these stats, they played a very minor role in actual gameplay.
Gameplay isn't all that matters, as you should know from PnP, and as far as video game RPG's go stats serve as a way to help reflect and further define your character in the game itself, as opposed to just in your head. In PnP you can get away with letting most things develop in your head, because that was your equivalent of a monitor. Your imagination was your gateway into the world you were playing in. With video games, however, the game is the gateway, and as such the imagination cannot be called upon so much, nor should it.
If you are almost dead and he wants you to be able to surprise that monster, he's still going to let you succeed in surprising that monster, regardless of your DEX score, or what the die landed on.
You realize this was the original purpose of Luck right? Or at least thats what I saw it as. Luck gave you the ability to overcome when otherwise your stats should have meant your utter failure.
For example, how would you feel about a game with detailed, old school RPG stats, but very poorly written quests, or not enough interesting factions to join, or absolutely no compelling NPCs?
The extremes go both ways you know, and neither is particularly favorable.
