In rpgs and such i tend to accumulate level ups so as to get more then 1 skill point/talent point/whatever to play with.
I dont like taking baby steps on a stat screen basically, it does lead to game being harder depending on how far levels up are, but well its a habit.
Otherwise what else...
Oh yeh in rpgs (again), if given the option i tend to make a character as close to me as possible for easier immersion.
Its only in subsequent runs i vary it up. Im one of those who contributed towards mass effect series being mainly played by male shep soldiers
Otherwise its all rather classic, i find it frustrating in most games to progress to next area if i havent discovered all the collectibles/secret i want to discover (so to use tomb raider as an example: tombs and relics, id be annoyed when realizing i needed an upgrade from later in the game and would go back to that area asap as soon as i got it, didnt care for the gps caches though so those didnt count in my book).
