Hmmmm... ...
I have only quit twice, once as a Berserker, and once as a Wizard Slayer.
The thing is, I like spell-casting and I know this, so I have always successfully completed the game when I play as a Sorcerer or Blade, because I was having fun. This is a very important factor! Without the fun factor, you get bored, weary and deary with your character, prompting you to quit.
I know fighters can be powerful and all that, but I dunno... the only 'fighter' type I like is the Paladin class, which incidentally, can also cast spells.
Also, I played a all-female party when I played as a Paladin, which I found highly entertaining and it spurred me on to continue with them because I developed an attachment to them.
Then there are the themed parties, I only played one so far, and that was as Robin Hood and his merry men( and woman), it was also the only time I ever role-played fully. Heh heh, restricting yourself can be fun too, no helmets, no armour better than chainmail, must stick to weapon type( gotta love Grandmastery in Daggers), etc... ...
The thing all these have in common, and I repeat myself again, is the fun factor. Before creating your character, ask and question yourself first. If you were borned in a fantasy world, what do you see yourself as? Do you prefer melee or magic? etc... ...
Since young, I have always day-dreamed of Mages and Sorcerers( thanks largely to Terry Pratchett, author of the Discworld series), so it was a natural choice for me when I got BG2.
Good luck and have FUN!

If not a Sorcerer casting total oblivion, then a Cavalier meting out justice. Otherwise, I think I will just be a Blade and torture my enemies with, "My Heart Will Go On".
