Archer (Ranger) or Knight (Tank)

Warrior, Paladin, fighter or as close to. Just your usual walking plank of wood

I preferedly play those classes, that the majority doesn't play

FPS - Always mid-close range :D
MMOs or RPGS - I like to choose melee classes or hybrid classes (played wow :P stupid druids) and sometimes don't mind healing. Casting/mage classes are only ok in my book :P

I suppose I go for brute strength in a lot of games that I play.

I'm always Bowser in Mario Kart (knocking players around like toys: beautiful ).
In Paper Mario, power plus badges are the way to go.
My second most used character in Brawl is Ganondorf.
In FPS' I love using the boomstick.
In Warcraft III I love making an army of Frost Wyrms.
I overused the Black Knight in Radiant Dawn (and loved every second of it).

So... uh... yeah.

I am always a caster on my first playthrough, a necromancer in particular if there's one...

Some sort of rogue or mage type, depending on how good the spells are. I'm always some sort of fast lightweight class though. The closest I've come was developing a Ranger/Cleric in Baldurs Gate 2, and a Monk with 2 - 4 levels of Shadow Dancer in NWN(still a lightweight dogfighting type character) I can't even remember ever having willingly developed a preference for a heavyweight type.
That also goes for fighting games: in SSB64, I majored in Kirby with a minor in Ness, Melee I started with Peach but migrated to majoring in Marth with a minor in Luigi/Mario/Ness. In Brawl I started as Marth but moved back majoring in Kirby, taking on minors for Marth/Ike/Lucario/ToonLink. Ike is the closest I've come to enjoying a heavyweight character.

My VERY first experience with D&D was Baldur's Gate, I created a half-elven fighter/mage who specialized in halberds and bows. Never realizing how important dexterity was, it was one of his lowest stats along with wisodm, but I was saved from the error of my inexperience by finding the gauntlets of dexterity, which raised my dex right back up to 18.

Yep, same here. I just think long-ranged casters/archers/snipers are for wussies anyway (look at Brawl, especially Pit/Wolf/Zelda/Falco/Lucario users)! =P

Quick and light armored range types, always.

In Mario Kart, i alwais chose 150 cc if you mean that.

In general, Normal difficult.
