And anyway, there's no law that states characters have to be 1st level when play begins. The last campaign I DMed (which was admittedly rather short), the PCs started at 4th. The next one will probably start at 3rd.
Oh no, I agree with Hong...
Yep, depending on your playing style you may well find that it's best to start PCs off at 3rd or even 4th level. In my own campaign world Ea, I recently twice tried to start campaigns at 1st level - and the party got crushed both times. I couldn't seem to reduce the inherent deadliness enough to make it survivable. Eventually I started the campaign with PCs of ca 4th-5th level (depending on XP allocation after transfer from another campaign - new PCs got half the XP total of their PCs from the other campaign) and this has worked great.
Also, when a new player who hadn't played 3e at all joined the existing campaign recently, he got to play a 5th level sorcerer who soon reached 6th level - fireball heaven!
He got to have a fantastic time and is now totally hooked. The hard slog up from 1st level might not have had the same effect. I do severely limit starting magic in my game - PCs start with gear of value equal to 'typical treasure for an encounter of their level' - 1200 gp for 4th level - enough to afford decent mundane kit, but not much in the way of magic - and I think this makes starting with higher-level PCs easier; I can run adventures for a couple of levels lower than their actual level and it works ok - advancement isn't too fast, the games are tough but survivable, and the magic gained remains fairly low.
