Depends on the quality of the game; if the game is rich in story, world-building and characters with an extensive and thought-out dialogue system and so on, I tend to gravitate towards an int/charisma jack of all trades kinda guy. As this kind of character is really immersive for me. however I'm not(sadly) intelligent nor charismatic IRL.
As I move through the world I generally try to make rational decisions that help the most kind of people, crushing hopes and desires of the poor fools who cannot see as far as I(lol) and, if possible, end the game in the worst way possible as a joke.
As for my characters stats, I have to agree with 1varangian; unless the game allows for more wonky builds, because strategy/environment/planning, is as important as getting that 20 strength or whatever.
If the game is bad, well just give me the loot and experience so I can finish it quickly(if at all).
