Warriors don't exist in ME (LOL), you mean the soldier class.
I played ME as a renegade vanguard. Found the game mediocre and sold it. I picked up ME2 after hearing about how haters of the first enjoyed it and thought it was an improvement upon the original and I myself actually enjoyed it more and even had the save of my first character. I imported him into the game and changed his class to soldier (because I found vanguard to be rubbish) and even made him a paragon - regretting his past renegade actions - but he still had a bit of renegade in him.
ME3? I'll pick that up when it's cheap next year or when a GOTY edition is released.
