Kind of something im a bit confused about. Besides some racial bonuses, I dont understand why certain races are more suited for certain types of play styles just because of starting skill bonuses. For example, a khajit starts with 25 in sneak and an orc starts with 15, but i can easily get my orc to 25 in sneak in very short time. since it seems that most skills are fairly easy to build up from 15 to 20 or 15 to 25, i dont see why it would be so much more of a pain in the ass to make a thief orc as opposed to a thief khajit or argonian. Im sure im missing something but any info that helps clear things up would be much appreciated as i am fairly new to the TES world.
See, it comes down to time. You say it doesn't take you long at all to skill up a thief Orc. You're right. But, the Khajit Thief that started off with the bonuses will still be ahead of your Thief Orc, given similar experiences, training paths, and time.
Does it really matter? Not really. But, to make the most use of your time, it's just easier to start with a race that gives you the proper bonuses. That's the beauty of the Elder Scrolls, you can do whatever the heck you want.
EDIT: If I recall, Bethesda stated during an interview that the character leveling is supposed to get faster when you level your higher level skills. Which would mean to me that a Khajit thief will also gain levels quicker than an Orc Thief that has to really work at getting his skills up. (Gotta try and find the article that stated that)
EDIT2: FOUND IT!
IGN: How will skill progression and the leveling system in Skyrim work? What sorts of decisions will need to be made upon a level up and what do you need to do to qualify for a level up? Is the improve-by-use skill system still in place? Will all the skills from Oblivion be used in Skyrim or have there been changes?
Todd Howard: Skill increase works like Oblivion, the more you use it, the more it goes up. The skill list is similar, but tweaked for the gameplay we have now. The big difference is in how you gain levels.
All your skills affect leveling. The higher the skill, the more it pushes you to the next level. So it's a nice self-balancing system, you're rewarded for using your higher skills. It urges you to focus. Skill increases become the equivalent of our XP for leveling. The higher your level, the more you need. When you level up, you pick one of your main stats to increase, and then you pick a perk. Perks are where a lot of the power is, and it's what defines your character, more so than your skill numbers. So each skill has its own "perk tree". And, those perks range from doing extra damage with a certain weapon to all new things like special moves, disarming and critical strikes.

So, moral of the story... does it really matter what race you use for what class? No. But the race that does what it is intended to do will excel more at it.
