I agree that it comes down to play preferences, or "styles", but 3E definitely did not support my preferred style, where the players play "characters" who have a long history and a worked out personality. I am not saying full immersion role play by any stretch of the imagination, but to have characters that own lands, that have a keep or even a castle or temple, who hold titles of nobility, and where owning and have these titles have an impact on what the character does and does not do.
Like my son plays a Paladin, has a 100 square miles of prime land. He even has several mines (lucky friggin percentile rolls), and has built a Castle and fortified town over a 5 year period. He has gone aon "recruiting" campaigns where he entices people to move to his lands, because he needs more bodies to work the land to its fullest potential.
There is a party member who plays a Druid (my Daughters). The druid and the paladin works together to make sure the land doesn't become overworked and ruined.
The Ranger (my other son), before he died, was helping develop the animal husbandry aspects, to make sure lands weren't over hunted, and even the herd animals were cultivated at the most balanced rate possible.
Whats their motivations? Money. Creating the best living conditions possible for their people and even their live stock. Not to mention the prestige they now have among the nobility. Plus enemies.
So they have many things to spend money on. Roads, Dovecoats, mills, fortifications, soldiers, churches and temples, recruiting new citizens, helping them set up homes, farms, and businesses.
So they not only go into "adventures" and slay demon princes (just finished DCC 18 last night) but they also take on the challenges of cultivating their lands, protecting their citizens, and dealing with jealous nobles who hate them for their successes, and so vividly illustrating their failures to properly manage their lands to the Empress.
Thats the kind of game I like to run. I couldn't do it in 3E. Not only because of the gold issues, but they would level so fast that they were powerful enough to just take the kingdom for themselves and eliminate all opposition easily.
So this is another reason why 3E isn't my "cup of tea", and is something I hope is taken into consideration with 4E.
Not that I am worried. I'm very happy with Castles and Crusades, so if 4E still doesn't do it right for me, I'll just steal what I like from 4E and keep on gaming the way I like.
