Theif Series (ACTION RPG)
The theif series is an Incredible series of 2 games (soon to be three) where you play the role of GARRET.
Garret started life as a petty theif who during the course of his childish pickpockiting, ran across an expert theif. He was caught and taken to a "theives guild" where he learned the way of theivary and shadows (which is how you start the game by the way...in training)
Soon Garret begins on a mission, which takes MANY turns from Theif 1 to Theif 2.
The main concept behind Theif was a GENRE breaking concept, the gameplay was like no other ever conceived before it. Everyone plays first person games with the idea of killing enemy after enemy in an almost RAMBO'ish' style until the game is inevitably beaten. But Theif takes a different approach, the main concept of the game was NOT to fight, and not to kill, Garret (ie: the player) was to manipulate shadows and watch the amount of sound he is making as NOT to take on the enemies.
So in essence this was the FIRST and in my humble opinion BEST FIRST PERSON SNEAKER
