Deus Ex vs Thief
Deus Ex
Deus Ex is the first game in the Deus Ex game series which has risen to fame and had gained a massive somewhat-cult following due to its second sequel. The game is incredibly old-school and hence, its graphics may put a lot of players off, but the game offers an immersively detailed storyline that is set in a rather chaotic year of 2052. You even get to play as a super-cool cyborg who has many amazing augments, skills and weapons at his disposal. The game is not all shoot and kill though. It also has many ways for you to avoid bloody confrontation, which frankly will definitely delight players who enjoy having alternative approaches to an encounter.Unlike many other games that adds in fantastical elements to enhance its gameplay, Deus Ex is a game that emphasize on the possible problems and issues that a futuristic human world may experience. It deals in conspiracy and the human nature rather than fantasy and that's what made the game incredibly unique back in the day (and this statement is also relevant until today).
Thief
Thief is a stealth-based RPG where you assume the role of the Master Thief, Garrett. Although he has been relying on his skills to survive so far, the revolution that threatens to break the gates, unleashing a bitter and bloody conflict between the upper classes and the common folk, will upend his life and force him to finally choose a side. With Garrett's wide arsenal of skills and tools at your disposal, you'll need to covertly infiltrate mansions, sneak across rofftops, and take out unwitting guards quickly and silently. The AI in the game is rather clever as well and are very well-aware of their surroundings, giving the game a higher degree of difficulty than you might expect.Every aspect in the game caters to the art of stealth, be it sneaking along a wall or quietly wringing a poor guard's neck. So, if you enjoy stealth-based games, you'll definitely love Thief.
