Numion said:You have sound reasoning in your posts. However my experiences differ from yours. I learned to play in the Basic D&D / 1st ed AD&D era, and our games were much more munchkinny, hack'n'slash and shallow than since then. Could it be that the players you've encountered are that way not because they started with 3E, but because they're younger (and thats why they learned with 3E)?
I'm sure that's part of it. Another factor is the style of the DM they originally play with!
If you have a DM who encourages role-playing over hack'n'slash (and assuming that your personal style is not biased totally towards hack'n'slash), then you become better role-player, regardless of system.
The converse is also true. If you have a Killer DM type, who you really need to be on top of the game rules to survive their dungeons, then your gaming habits are shaped that way.
Most beginning DMs are of the hack'n'slash school, because it's the easiest way to begin. (e.g. there's a room with an orc and a pie. Kill the orc!) There are examples, possibly from those with more literary, theatrical or maturer viewpoints, who will emphasise elements other than hack'n'slash.
Cheers!
