Baldur's Gate Enhanced Edition

[Winthur]

It gets better once your mages reach level 3 and can drop Web or Stinking Cloud on the field. Then you can pick off the immobilized enemies at your leisure.

Oh yeah, it's worth noting that at the early levels the crowd control skills rule. A Druid's Entangle is great, my personal favourite is Blind because of how gamebreaking it can be. (Seriously.) Magic Missile isn't really too good until you can cast more than one in a single spellcast. Fireball or Lightning Bolt are the first blasting spells that I like.
