Right.
I also wouldn't worry too much about slow progression in spell levels in the computer rpg.
On PnP it can be frustrating to have a cleric/mage who takes endless hours of game play to get new spells, while single class characters are increasing their skills, feats and spells rapidly.

I can't think of a Black Isle game where the multi class characters didn't reach maximum level for the game before it ended.
That should be the same for IWD Jr. (Barring your taking a new class at every level that is)

Just remember: the computer DM gives out 50,000 xp to every character for things like finding a child's lost dog. PnP DMs, on the other hand, might consider giving you the xp for killing the dog if it put up a good fight.

So, multi class away. Think of how useful Arie was in BGII with fire of vengence (Cleric spell) and horrid wilting (mage) in her arsenal.

Multi class away!
