Yup! I say it is the DM's call at chargen, especially once consensus of the proposed campaign (theme, genre...etc) has been agreed upon by all.
but in order to get there... drum roll please...
You NEED TO AGREE....
all of the problems disappear if you agree, by its nature this thread is about what happens when you disagree.
And for heaven's sake all you DM-bashers, we are speaking of reasonable DMs.
except that is the argument... what makes a DM Unreasonable?
lets take 4 DMs (at least one of these is me by the way) lets see if you think any are or are not unreasonable.
1) The DM shows up to a 3.5 game with a binder, in it is a 20 page expanded history of the world (also has a 1 page hand out with condensed version) a list of races allowed (human, elf and half elf from phb, Elan from Psi hand book, and two races from incarnum) mixed with 2 new races (one is a kender like race, the other a dragonborn like one) and a list of classes 15 from the books and 2 full homebrew classes (the magister and the ravager) and a list of 22 prestige classes from diffent books, and 18 home brew (some just modified from books) Prc. He tells the players they will be starting in the floating city on the east coast of his 7 page fold out map.
One of the players says "Um, are you crazy, is this even D&D anymore?"
2) 5e playtest. The DM has watched WAY too much game of thrones, and wants to run a game where there is a lot of political infighting... human only, no spellcasters.
all the players to one way or another ask the same question "Is this worth play testing next? wouldn't fate or something fit better?"
3) 4e game The DM takes a piece of graph paper, puts a dot on it, lables it a city name. Then takes out a single sheet of paper writes the name of the city and 4 NPCs and 6 Locations all within the city. Then says "OK, so lets make some characters"
Some players start thinking, but one says "How can we make characters with no idea what the world is like?"
4) set the way back machine to 2e, and the DM says that this world is ruled by an alliance of Gnomes and Kobolds and Dwarves. It is a world full of technology, and you will be part of the reblian against this evil empire... races allowed are human, hafling and elf, and spell casters only, level limits strictly enforced
Sorry to say this, but I feel it has to be said, it sounds like many of you have DM-issues to work over cause your scars seem deep.
maybe instead of pretending the issue is 100% on my side of the discussion we can say we all have had some issues, becus the deep scars from 'bad' players seems stronger still from where I am sitting
