The storyline of Niko Bellic making his way through the ranks of Liberty CIty is just amazing and will keep the player engaged till the last mission. The environments created in the game are very realistic & spectacular. In short this is just an amazing game.
Not to mention that the multiplayer too is amazing and fun, especially when played with friends.

There are games and there is Super Meat Boy. It takes Meat Boys journey hrough hell and beyond in the search of Bandage Girl.

Yes the game probably is one of the most difficult games of all times, but when we do complete a hard level the level of satisfaction is HUGE. There's a sense of huge achievement. With a great soundtrack(which played a major part in keeping me going to try a level dying multiple times) this game is a journey one musn't miss.
Must play for just about everyone(irrespective of whether one plays or doesn't play Indie games, this place won't dissapoint)

PS- A Controller is recommended while playing this :D

A great puzzle platformer. A 2D game in a 3D world. Love the art and soundtrack. Must play for all indie lovers!
