I wont try to order them because I love them all for different reasons, which I will in fact mention.
The 2 that came out last year( the shining beacon of glory in the sludge of pure shit that was last year) are:
Transistor-Amazing music, still listening to it. Great combat, perfect story. My only complaint is that the challenge mode bosses read your inputs and thats cheating, rest of the game is perfect though.
South Park The Stick of Truth: It is the perfect transition from the show into a game. I cannot recommend it enough if the game trying its best to offend you sounds like a great time. O god so many perfect moments that I wish I could mention but it would spoil the game so I wont.
Killing Floor: It's what evolve wishes it could of done. It's JUST a horde mode... but the game feels so good that years later its player base numbers mock evolves. It's gory and beautiful and the guns feel great.
Super Mario RPG: If you have to ask, you're a horrible person. Top notch RPG, with brilliant music and combat, the plots hilarious and the only gripe is that its too easy, but well worth playing regardless.
Tactics Ogre Let us Cling together: You like Final Fantasy Tactics? This is FFT only better polished. If you have a PSP or a VITA, buy it NOW. If not, buy a vita damn you! Its a better handheld than the 3DS
.
The Secret World: A Greatly under appreciated MMO. There are no "classes". You make your own build from over 100 skills that you pick and choose. Theres also no levels. Then theres the absolutely amazing story and incredibly difficult research missions. They also have the best B2P model in the MMO genre.
Jade Empire: Back when Bioware was good. Like Kotor? This is an epic Martial Arts game in the same vein as KOTOR, only it works way better, is way deeper and has an amazing combat and story system. It's on steam right now, get it!
Saints row(series): I just can't pick one, I'm so sorry. They're all great and everytime I play them I'm screaming and laughing at how badass it is.
Vampire the Masquerade: Bloodlines: Buy it, install it, install the unofficial patch, profit. An amazingly deep RPG with great characters, sweet music and where you get to play the monster.
Fallout 3: Such a great game, pure exploration fun. Sneaking through tunnels, sniping mutants, talking to tree, find lost lore. So great.
