Crysis vs Thief
Crysis
Crysis is the first of a brilliant action-shooter game that has players shooting aliens and saving the world with a unique, multi-function nanosuit that augments your combat capability on the battlefield in ways that kinda makes you a super-soldier of sorts. You can enhance your strength in order to lift cars, for example; boost armor so you can take more damage, or turn on invisibility to sneak through enemy lines. There is a diverse arsenal of weapons and munitions that you can use and customize as well, giving you multiple ways to plan out your tactics and play according to your own preferences.As amazing as the first Crysis game was, the game's graphics can be a bit dated and well, none of the online servers are up now, so you can't really enjoy the game via its multiplayer mode. However, if you simply want to enjoy the game for sentimental purposes or to enjoy the storyline, well, you might want to buy the game.
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.
