Bookwyrm627: Don't make a rogue. They have issues dealing damage to creatures that are immune to sneak attacks.
Fighter/Rogue, on the other hand, is a very solid approach. Use the combat style of a melee fighter (heavy armor, strength-based melee weapon) and supplement it with the skills of a Rogue. You'll generally pass on stealth with this approach, but otherwise you get the best of both worlds. Take your first level as Rogue, your second level as Fighter, then balance to taste (I prefer a 4:1 ratio in favor of Rogue). Definitely one of my favorite character builds, if that's not too complicated for Sawtooth.
Straight fighter, barbarian, or cleric would definitely be a simpler approach. I'd agree with MagicalMaster that Monk isn't recommended for a beginner. Definitely find a build order and follow it if you want to do Monk, they're easy to screw up. Sorcerers are fun, but the tricky part is that you can only change which spells you know when you level up. This makes it difficult to try new things, and it can put you in a very tight spot if you encounter enemies that you lack spells to deal with. Remember not to go overboard with damage-dealing spells, you only need a handful of them, and it's more important to carry a wide variety of spells to give yourself more options.
