The greatest advancement of the computer game is that every single little sub-possibility when it comes to character creation has a little box next to it that can be checked or unchecked at whim. Do you want to make a svirfneblin rogue? You can! Put him in a party with a half-elf paladin, a half-orc fighter/druid, and a dwarven kensai!
The main thing that I’ve noticed when creating computer game parties is that the temptation to create a svirfneblin rogue are just as great as when playing a tabletop game, but far more easily dismissed when you realize that you won’t be able to make a game out of making everybody else correct your pronunciation of “svirfneblin” (“svear-fne-blin” is, apparently, the canonical pronunciation).
But then, when you start to play, you realize that you should have gotten a bard because there are sweet bardic items that just lay fallow if you don’t have a bard in your party and that dual classing is the only way to go because it’s a computer game and your backstory that you spent three hours writing is pretty much useless. Also, there’s a sweet fighter/mage item and only fighter/mages can use it.
Temptations to create a specialized mage who specializes in offensive spells should be avoided given that you will find yourself needing an “identify” spell a lot more often than you’ll find yourself needing that fourth magic missile spell.
And you need to seriously tempter your clicking finger when rolling your character because a roll in the 70’s is good, a roll in the 80’s is great, but a roll in the 90’s is undone in an instant because you’ve just been doing the “click, click, click, click” thing for 20 minutes trying to get that ever-elusive roll that will let you have only one dump stat for your character instead of two (which, when you’re playing dual class, is the most important thing in the world).
And keep in mind: turn undead is useless.
So, with that said, you need:
A Paladin that specializes in sword/shield
A Fighter/Druid that specializes in club weapons
A Ranger that specializes in bows
A Cleric/Mage to be the Band-Aid box
A Cleric/Thief to be the other Band-Aid box
A Bard to keep those sweet, sweet magic items from going to waste
So… what are you playing?
