Mass Effect 2

Each new recruit has a personal quest you can tackle before setting out on the final mission. Completing a personal quest unlocks a new power and costume, and cements that character's loyalty to Shepard and the mission. Though technically optional, these diversions are the strongest part of the game and you're missing out if you don't play through all of them. They invariably contain a shocking reversal, a moral quandary of some description, and variations on gameplay that go beyond simple combat.

Games like Mass Effect 2 don't come around often enough. Look at any aspect and you can be sure it's great. It's incredibly personal while still retaining a sense of epic sweeping scale. The combat and mission design are outstanding. The visuals, voice acting, soundtrack, and direction are miles ahead of the competition. Perhaps most impressively, Mass Effect 2 manages to fulfill its incredible ambition while only suffering from very few technical hiccups.

From a tactical standpoint, you are no longer shoehorned into relying specifically on Shepard’s class specialties. You can snipe from ridges, create biotic and firearm combos, and even use melee/shotgun-style assaults. All of these options feel great, and are balanced to create exciting battles.
